correct suspension black

    Recommended Posts

    I am painting my suspension but I switched flattening agents and the new one makes it much flatter than the old one.

    I am trying to figure out which one is close to correct

     

    This is the early flattener I was using not very flat. Fairly glossy and looks nice

    This is the later flattener. Much flatter. almost no gloss

    Cross member is pretty flat too

    Table full of parts

    Can someone give me some direction on which finish is correct. The glossy one is the easiest but I'd like to shoot for the most correct finish.

    Based on what I've seen, it's more of a "satin" black, but then my parts are 43 years old.   They may have been gloss from the factory...

    Cliff,

    Is "gloss", really glossy or sort of glossy?

    This was the tube on the steering rack and it was gloss.  I'll look at my other black parts I have in a box for sand blasting, I'm thinking the trans mount is gloss too.  Maybe the chassis parts are satin and the other is gloss?

    I thought I had a picture of it before I stripped the paint off.  :)

     

    It's not greasy I promise, I hate handling greasy stuff, so you decide how glossy it was.  This is off my orange 240.

    The powder coating I am doing on my suspension pieces is 50% gloss black and looks correct when matched with various sections of the original unrestored suspension pieces that still have shiny black paint remaining. This car has 24k miles so there are quite a few areas where the original black shows up well. 

     

    Of your two examples the gloss looks closer to me to original than the flat. I agree that a satin would be best.

    That's pretty glossy. Obviously glossier than the crossmember and dust shield.

     

    I will aim for the gloss finish I already have. That will prevent so much rework.

     

    Thanks Guys

    I just remembered where I've seen the same black sheen as the steering rack.  The metal ring around the hole in the tunnel for the shifter, under the boot.  I knew I'd seen it somewhere when I was tearing my car apart.  Maybe they painted things in groups?  But I like the gloss you have in the very first picture of post #1 too, less work is always better. :D

    Well I finally came up with something I think will work. It took several test panels to get it where I think it's right.

    I used Nason FulCryl II single stage mixed 8 : 3/4 hardener 483-11 : 1 1/4 reducer 441-21 when mixed to 6 sprayable oz's add 1 1/2 oz of Limco LF-10 flattener

    So a couple of weeks ago we scuffed everything down...

    20160409_105050.jpg20160409_105101.jpg

    Hung it all back up in the booth

    20160409_152239.jpg

    Made it all black this morning

    20160409_152252.jpg

    The sheen is pretty good. Has some sheen that you can see but not real glossy. If I had to do it over I might use the Eastwood satin but I have seen some issues with people having adhesion problems. The Nason has never been any issue. Sprays well and sticks really well. This is shot over Omni epoxy primer....

    Time to order some bushings and get moving on reassembly

    Here is my replacement tank, just recently removed. It has quite a high gloss compared to the suspension components.  Replaced in 1985 at 134,600 miles and now has 147,600 miles, so only about 13,000 miles. $195 list price and I paid $156.  Wondering now why I didn't stock pile more parts.

    While not suspension, I have these reference pics of the manual transmission cross member mount.  Can't imagine that the paint used for this would be different than the suspension, but I do not know for sure.  Maybe useful to someone here (click for bigger image):

    Good pictures!

    I have come to conclude the paint was probably glossy from the factory and became satin looking over time

    Based on what more sheltered parts (eg steering column) looked like, I looked at what the powder-coat shop had on offer and went with a semi-gloss black that they call "machine black."

    A few more reference pics, this time of a motor mount and driveshaft: 

    IMG_20181016_202037.jpg  IMG_20181016_202102.jpg  IMG_20181016_202124.jpg

    IMG_20190112_175241.jpg

    The pedal box and steering column are quite glossy.  However, the heater box, and fan, are not - they are semi gloss.  And then there is the brushed on paint on various parts of the interior like around the kick panels, the rails that the seats bolt to, around the quarter windows, etc. which is very dull.  The suspension is quite possibly a unique level of gloss vs. the others.  I will be looking for some reference shots online before I paint the suspension of the car I am restoring.  

    The following pics are of actually the same paint.  The pedal box is before adding any flattening agent. 

    IMG_20190225_182936.jpg  IMG_20190225_183026.jpg  IMG_20190225_183112.jpg

    The steering shaft and pedals are after adding 10% flattening agent and letting the paint sit for bit.  I found that adding agent didn't work instantly.  It took a certain amount of time (like 30 min) before effect was very noticeable.

    IMG_20190225_183128.jpg  IMG_20190225_183140.jpg  IMG_20190225_183150.jpg

     

    And then I made the mix 20% flattening agent and again had to wait.  But there was quite the transformation:

    IMG_20190225_183228.jpg  IMG_20190225_183248.jpg

    Same percentage - used on these panels inside front fenders also:

    IMG_20190225_183212.jpg  IMG_20190225_183302.jpg

    It is a nice satin.  Good for some areas, no doubt, but not for the mustache bar; I do not think.  Hopefully, my experimentation here is all of that I needed to do.  I plan on doing the suspension with the 10% after I let it sit for 30 min.  I might do 5% wait, spray, then 10%, wait and test to confirm, and spray.  Luckily, this stuff doesn't require a catalyst, so it can sit and sit.  

    I also have a bunch of reference pictures from the $300,000+ 240Z that was on Bring a Trailer; I suppose putting a few here wouldn't be a bad thing, right?

    I missed the part  you said what you are using, powder coat, paint?

    Given that many of the component parts on these cars were made by different companies and/or affiliates of Nissan and Nissan Shatai, I would not necessarily expect them all to have been painted with exactly the same material, or to the same standard/thickness/sheen.

    Just paint.  I am sandblasting most parts, and putting a quality primer on before painting with an enamel.  As far as I can tell, there is not primer from the factory on any of the parts being discussed here: suspension, pedal box, steering column, heater box, motor mounts, transmission mounts, etc.
