Project Boondoggle (or, so I went and bought a Z!)

Recommended Posts

First coat of silver went on the floor pans this evening.  The DIY supplied air contraption worked a treat!  Better than the mask (though more awkward).  I'll have my wife take a photo of it in use when the second coat goes on tomorrow.  Wish I could've read her mind when she got home today when I was in the middle of this project!

I always tell my wife I have better judgment than her. After all, I picked her, she picked me....

Progress!

 

Two coats of the Masterseries Silver have been applied and it looks a lot prettier now.  I spent yesterday evening masking off all the areas that needed seam sealer, which ended up being a ton of work I probably didn't need to do.  Since I don't have a gun for the 2k sealers, I chose the 3M Ultrapro.  I also don't have a gun for that, but thought I could do the old homemade pastry bag trick.  Turns out that seam sealer is way thicker than frosting!  Spoiler alert: it didn't work :)  I ended up digging the stuff out and applying it with my fingers, which made a pretty horrible mess and isn't something I really feel like doing again, but it came out nice enough.  Hopefully on Wednesday I'll have time to put on the black finish coat.

Looks good. Make sure the bottom side of those seams are sealed up good, they are the bigger issue

More floors!  Got the top coat of paint on and then some Raammat I had left over from the audio install I did a few years ago in the G.  A lot of people like to put this stuff on with full (or even overlapping) coverage, but that generally doesn't work well.  Those sheets don't block noise, they reduce panel vibrations, so I stuck it in places that sounded the worst with the very-scientific knuckle test.

To block the sound, I'm going with mass-loaded vinyl and closed-cell foam.  I used this in the G as well, with good results.  Here my plans start going sideways.  Originally wanted to cover the whole floor with MLV, and even made a very elaborate template that took a lot of time and back pain, which isn't going to be used.  The old MLV I had left over probably would have worked with enough finagling, but the new stuff (from the same supplier) is about 25% thicker and a good bit stiffer.  Here's a comparison, and you can see how the old stuff lays in better on the passenger side than the new stuff on the driver side.

So the current plan is to scale back and use the new stuff on the flat sections of the floors, lay the old stuff over the tunnel, and not be so fussy about getting it to fit, since it's all covered by carpet anyway.

I'm doing my best not to think about the bottom side! :)

I'll take that on whenever I can finally get to -- or farm out -- the body work.  Fortunately the Z only goes out in fair weather and spends the rest of the time in the garage... (kind of like me...)

I'm going to be eager to hear how quiet your Z is after properly sound deadening it!   I'd love to do the same thing, but i'm scared about how much weight i'll be adding.  Any idea what it will total?  Great work so far!

i used sound mat (tar-like adhesive side w/foil top surface) throughout the floor pans, inside of the door skins and on the underside of the roof and then followed with a heavy, rubber-backed carpet with thick jute backing and it made a significant difference on my 280. later i did the inside of the spare tire well and was impressed with the further quieting that occurred. the tire well rings like a bell to the knuckle and after sound mat just a dull thud. seems like the high frequency noise was most removed, kinda like turning down the treble knob on the road noise. the doors sound a lot more "solid" with the sound mat, less like a tin can. i bought the sound mat in a roll and had plenty, so i did the whole floor pan and tunnel - not sure if it was necessary, but i was in there so just did it all.

Onward with sound deadening.  I screwed up on my order and bought 1/4" closed-cell foam mat instead of the 1/8" I'd used before.  That's a comparison between what I had left over and what I bought.  It's fairly expensive stuff, though, so I ran with it and hopefully it won't be a problem when laying the carpet.  I did a couple test fittings and I think it'll work okay.  A few pictures of the whole process, which is basically just a lot of measuring, cutting, sticking.

IMG_3827.thumb.jpg.2d1fe3d350dd9bcabda89IMG_3826.jpgIMG_3828.thumb.jpg.70660b10bed0f4c91791cIMG_3829.thumb.jpg.0cc0f2e4284998557ec9aIMG_3830.thumb.jpg.ac45bf1699e47d267bb19IMG_3839.thumb.jpg.2ae55428e89d743d82c41

Oh, I was clever and did this with the leftovers.  Should've thought of it weeks ago.

IMG_3833.thumb.jpg.e1d04a559e26bca70e750

As for the weight?  It's heavy stuff: 1lb per square foot.  I didn't measure, but I'd guess there's probably about 20lbs total in the car.

Santa brought me the ACC carpet kit, which I'm diligently avoiding installing at the moment, since I don't yet have the nerve to start cutting it up :)  So I decided to start cleaning up the rear deck a bit instead because it -- like everything else -- was disgusting.  Shots before, after using detergent, and finally the steam cleaner.  Still not entirely happy, but I may call it good enough until I get around to stripping and painting the rear deck.

IMG_3820.thumb.jpg.0601fe4d7e9b470b4dd4dIMG_3831.thumb.jpg.61fa73c429a9a593fab03IMG_3832.thumb.jpg.853db9fae2602e5db9844IMG_3834.thumb.jpg.e5fe29b6c1f4d9f31bf6dIMG_3835.thumb.jpg.83723974360282401dce7

My great victory for the night was on the wheel well and tower vinyl trim.  Even after scrubbing and steaming, it was still deeply dirty and stained.  On a whim, I tried wiping a stain with acetone, which took the stain and a lot of accompanying grime right off.  I went through 6 paper towels that all look like that one before calling it an evening, but already the trim is back to life!  Too bad about the rips, but I can put off replacing for a while until the budget allows.

Updates on some of the smaller things I've taken care of here and there.

The scuff plates were in bad shape, so those were stripped (which took longer than I'd like to admit), hit with the wheel and knocked back into shape.  Since I was planning on going through the trouble of painting them, I figured I may as well do the same with some of the other bits and pieces that could benefit from some attention.  All were given a brushed-on coat of the MasterSeries silver paint.  Not exactly original, but better looking.

IMG_3809.thumb.jpg.44e0368b87c207a684d37IMG_3906.thumb.jpg.f9c41f13ea38e62fbe86cIMG_3907.thumb.jpg.cceec81b9530ce2fe2208IMG_3909.thumb.jpg.059e7b2d4ca5b50bea64aIMG_3908.thumb.jpg.14918e1b75501369518c7IMG_3910.thumb.jpg.6115af8a8e8cb7e76a59b

Also dealt with the seatbelts, which was a gag-worthy endeavor.  Delightful things found in the passenger seat belt included: a quarter, a nut shell, and chewed gum.  The belts were soaked in hot water with Oxy Clean, rinsed, hit on both sides with the steam cleaner, soaked again with Oxy Clean, then rinsed twice.  That nasty water was from the passenger side; the driver side was significantly worse!

IMG_3814.thumb.jpg.43ebcad9d30504dc85b7cIMG_3813.thumb.jpg.996dcf0ec96ae7055fab1IMG_3821.thumb.jpg.3064510e4ed9480533da9

It was well worth the effort, though.  They don't smell anymore, nor give me that vague "ewww....I need to shower" feeling whenever I have to handle them.  Only hiccup: I dropped it on the way out to the garage!

i went through the same drama with the scuff plates - took hours to get the nasty curled-up vinyl wrap off and wire wheel them down to clean metal. i tried to re-wrap with vinyl but couldn't get anything to stick well enough so i went with black epoxy paint and they've held up pretty well.

when i cleaned out my seat belts i found corroded coins, cigarette butts and several false fingernail tips (ewwww!) inside - they work better now...

Glad I'm not the only one that struggled with it!  I plan on re-wrapping them (or at least trying).  I grabbed two different vinyls at Joann and was able to find a retailer that shipped Weldwood HHR contact cement to me here in CA. If that doesn't work, black paint or bedliner it is.

Charlie,

When I first got my car, my driver's side seat belt webbing was badly frayed. I have since replaced the whole assy with a donor in better condition and then took the old one apart to see what made it tick. With that in mind, I think I have a plastic side cover sitting in a box that I would be happy to donate to the cause if you're interested.

If so, shoot me a PM and we can chat.

I saw a post on another forum a little while ago from a guy who got hit in his Z.  His belts looked in good shape but snapped on impact.  He bashed his face and nose on his steering wheel and looked pretty messed up.  The polymers used in the belts are susceptible to degradation from sunlight.  They can look fine but actually be severely weakened.

If there are any vendors out there who want to develop a new product, bolt-in replacement belts would be an easy sell, I think.  We're all surrounded by SUV's and distracted drivers these days, plus many have grown accustomed to having an air bag in their other cars.

Zed, I thought about the same thing.  I saw a handful of threads on various other boards that say the webbing should be replaced, but not much definitive on subjects like when, how likely the belts are to break, or the loads that would cause it to happen.  I suppose the relative lack of I-almost-died posts that I've come across makes me think it's a relatively low risk decision to stick with the belts I have for now. Hopefully I don't Dunning-Kruger myself into the steering wheel.

Captain, PM sent!

Things have been moving along. Took that first cut and started with the carpet. It's the ACC kit, so it takes some work to get it to fit (I took a number of pictures and some notes with the intent to write up a how-to, since I couldn't find a detailed one), but it came together well, especially considering all the extra sound dampening I put in.  Too bad I accidentally tossed the rubber trim pieces for the seat belts.  Started working on the front half this evening, which -- after wrestling with the cuts to get it under the dash and into the footwells -- seems like it'll go a bit quicker.

The one thing I've flip-flopped on at least 5 times already is whether I should put the carpet over the seat rails, or bolt them on top of it.  Right now I'm leaning towards on top.

Other things...lots of visits from my UPS and USPS friends!  All my floorpan plugs needed replacing, but I blanched after seeing Nissan's prices.  I got a full set of replacements on eBay for ~$40 shipped by getting parts for Jeeps and Fords.  Interior Innovations finally shipped my shift and e-brake boots, and I got the supposedly-not-legal-in-California contact cement and re-wrapped the scuff plates.  And I splurged a bit on a new shift knob.

Hey Charlie,

Great job on those floors, soundproofing and carpeting. Just wanted to point out (having done the process recently) to be aware that if your material (foam, soundproofing and carpeting) are layed on the drivers side transmission tunnel they might push the position of your foot on the gas pedal over toward the brake pedal. Depending on your shoe size, this could be an issue.
