Dash Repair Process/Pictures

    Recommended Posts


    Well add my name to the list of successful dash repairs.

    I followed Bruces instructions to the "T" and couldn't believe how nice it came out. I did my repair with the dash still in the car but with the windshield out. Not the best but it was workable.

    Here's a couple things I found during my repair.

    I drilled tiny holes at the ends of the cracks to check the crack from spreading.

    Make sure you remove enough of the black dash material next to the crack. Mine was warped upward. I didn't cut it far enough back and when I started to feather out the filler I broke through immediately.

    Make sure you have a thick enough layer of bumper repair over the crack. I sanded it too thin and when I pulled the car out in the sun it cracked again. I would try and leave at least 1/32" thickness over the crack and feather it out 2" or more on either side.

    I'm still amazed at how good the dash looks and how easy it was to do. I keep looking at the dash and just can't believe how good it looks.

    Thanks again Bruce!

    Bruce, how did this hold up to the Arizona weather? I'm thinking about doing this to my own dash, for the 3 cracks I have are getting bigger, and starting to get another...

    Bruce, it has been well over a year since you have done your repair, any update? I am planning on following your process this weekend, but want to make sure that there isn't anything else I should know. I share the AZ sun and the damage it can cause!

    Thanks!

    I know it's not long term but mines still holding up fine from January. I'll emphasize again that the SEM bumper repair has to be at least 1/32" thick over the crack. If not it will just crack again. I speak from experience.

    The bumper repair just looks like regular old epoxy to me.

    That's surely due to this picture:

    But I can assure you that it isn't "regular old epoxy", regardless of what the picture seems to portray. SEM Bumper repair, IS mixed from two halves, but after curing it does retain a rubber type feel to it and does bend to a degree.

    "Regular old epoxy" and I presume you're referring to something such as JB Weld, or the like, cures HARD.

    Thats good because if it did cure as hard as epoxy it would definitely crack. However I still think it must be some special form of epoxy, may just not "regular old" epoxy. Anyways I guess the results speak for themselves.

    I was able to finish my autometer install in my dash that I repaired using this method

    I am planning on doing this to my Dad's dash. The problem I have run into is that the previous owner had a dash cap on it and there is a bunch of 3m type strip calk that held it on. Does anyone have any tips for getting this off. I have used a plastic paint scraper to get most of it off but there is still some on there and the dash is so dry that I keep getting little cracks in it.

    Thanks

    If it's Strip Calk, acetone will remove it as the calk is tar (asphalt) based.

    If on the other hand it's some other form of adhesive, you may have to resort to a 3M Strip discs, they come in different colors, maroon, blue and brown. They'll be the least agressive method to removing that other than other solvents.

    Additionally, you could use some of the Rotor "finger" discs and be careful as to how much pressure you use.

    FWIW

    What sizes of gauges are those that you installed?

    I ordered all me SEM stuff to do my dash repair. When I got going, I found many places on the top of the dash that looked good, but when you pushed hard on the plastic, it cracked. So I went carefully went over my dash hammering the plastic cover to find hidden areas that would develop cracks over time. Of course I ran out of bumper epoxy. None in town. Only two weeks to go till Walla Walla, car show weekend (Wheelin Walla Walla) and I,m sign up. Crud!!!! Well I ran down to my NAPA store and talked to a guy I know that works in the paint and body section. He said use NAPA flexible bumper repair. That this is what allot of body and restoration shops are using.

    I would just as soon stay with what is proven to work, But I really was in a fix.

    I know the following:

    1. It soaks into the foam better than the SEM bumper repair epoxy.

    2. It is allot more flexible when cured.

    3. It is easy to sand.

    4. It adheres to the plastic dash as good as the SEM epoxy.

    5. It cost $32.00 vs the cheaper SEM but your get about 4x as much.

    6. And only time will tell if I made a mistake by using this product.

    At least my Z will be ready for the show.

    out of curiosity, it has been over a year since the last post on how the dash is doing from the repair. Any news on how it is today?

    Diseazd owns the car with the dash that was repaired (at the start of this thread). This was his update as of May 2008.

    Real good info. I make sure I have a windshield screen to block the sun when not driving. At the very least, place a towel over it when parked. I think the UV rays cause as much damage as the heat.

    The dash is still "as new". No problems at all......the car is kept in a temp controlled garage....that may not be a good test lab vs. a car left outside. Bruce did an awesome job and an awesome thread. Guy

    Thanks Guy!! Glad to hear the repair has stood up so far, keep us updated so we'll know if this is a long term solution/repair.
