Fixing a cracked dash pad
Anyone ever used bondo to patch the cracks on their dash pad? I would imagine it turning out halfway decent if it is done right

Re: Fixing a cracked dash pad
The hardest part would be matching the texture. It may look good for a while but they 2 different materials will expand and contract and 2 way different rates so it will probably crack back fast being hit with the sun right next to the windshield.

Look what I found.
http://www.urethanesupply.com/produc...stype=products You could do like I said, trim the turned up edges on the cracks, apply this stuff to fill in the cracks, sand everything down, spray with truck bed liner and paint. As far as the speaker grill I think I would just fill it in. Nobody uses them anymore anyway.

Re: Fixing a cracked dash pad
I used expanding foam and shaved/sanded it down, also wanted to make the dash contoured so I used it as filler. Then I wrapped it in pergo [you know, hardwood floating floors] foor insulation before using two layers of fabric. Honestly it was thrown together but turned out better than I had expected!

Re: Fixing a cracked dash pad
It won't work for the reason given by Black Sheep 454. Bondo is meant to go onto rigid material and the dash pad is soft vinyl over foam (flexible). They crack because they lose their flexibility

Re: Fixing a cracked dash pad
theres a bunch of people over on my car forum (common problem to have a dash pad crack on 3rd gen f bodies too) that full the cracks with a sandable flexible epoxy then wrap the dash in vinyl. they usually turn out looking good. there was even one guy who fiberglassed and airbrushed his.

Re: Fixing a cracked dash pad
if you fiberglass the cracks first you can use bondo as a filler to smooth everything out.

Re: Fixing a cracked dash pad
check this link out....Basically you have to sand down your raised spots, use alcohol wipes, and then spread adhesive on your dash..This will lay over it and look great!

Re: Fixing a cracked dash pad
Trim down the turned up edges around the crack. Fill in the cracks with Great Stuff foam. Spray the entire thing with spray can bedliner and paint to desired color.

Re: Fixing a cracked dash pad
I used flexible epoxy oon mine, and painted it. You can still see the cracks from sertain angles. But it was easy and didnīt require much work so Im happy with the result. Itīs a bad picture. But you can see a small ridge just over the steering wheel. I will take it out at some point and wrap it in tweed, but for now itīs good enough.

Re: Fixing a cracked dash pad
Itīs similar to silicone sealer, the stuff u use to seal windows and frames on a house. But this stuff acts like a glue and you can paint it. I used something called Sikaflex, you can all so use windshield glue ( used on cars that donīt have a rubber seal like our trucks)
Just lay a bead in the crack and level it up with piece of plasticard, like when you apply bodyfiller. When it has cured you can trim it down with razorblade or a sharp knife if needed. If the edges of the crack are sticking up put a piece of plasticfoil over the crack and weight it down with something while curing.

Re: Fixing a cracked dash pad
That looks good. I bought one like it for my 79 from another vendor on line. The thing to remember with these things is that in 78 I think Chevrolet moved the VIN number to the dash from the door post. If you have one of these you have to either cut a hole in it so the VIN is visible or don't apply the adhesive. Mine looked too good to risk messing it up by cutting a hole in it so I did not use the adhesive. It's been on the dash for close to a year with no problems.

Re: Fixing a cracked dash pad
I think they moved the VIN tag to the dash in 1979. I have a 78 parts truck and it seems I remember the VIN tag on the door pillar on that one.
