i was going to try and fix my cracked dash. i was going to ruff up the dash w/ 36 grit sandpaper and then put a very light skim coat of plastic (bondo) over top of it to smooth it out. will the plastic adhere to the vinyl and would this work? if not does anyone have any suggestions?
 
There are products on the market made for this and I've tried a couple. Hard to get the colors to match so that the repair isn't obvious. If looks matter, I think you might be happier just replacing it with a junkyard find.

Ryoken might know how to best advise you tho.

Skigirl is right, in that you might be better off replacing the whole dash.

If your trying to do something "special" - Yes, you can try. It depends on how bad the crack is- if the crack is a warping- (which mine was), your method may be temporary, and as the weather changes, may crack again. Bondo isnt very flexible, and if you notice your dash, (unless its newer than 91) is made from a foam back/ vynl ish top.

Thats said, people do coat their dashes and paint it over- you'd probably want to use a fiberglass bondo for the base and cracks, and blend into the whole piece. That should increase your strength.

If you really want to minimize any chances of cracking- lay down fiberglass weave and epoxy it. Then bondo/sand the top. Even if the fiberglass seperates from the old dash, it decreases the chances of the top ever cracking.
 
instead of a cover i'll just buy a new dash pad. i just want a temporary fix till i get the money for a dash pad or find one in good enough shape. its such an eye sore cause its right above my gauges. once i got it all smoothed out and nice i was going to dye it or paint it to match my interior. im not worried about it not matching exactly... i just want it close
 
I had the same problem on my 81 Chevy truck. Bought a dash cap (?) . It is a thin hard plastic cover. It has been on the truch for 5 years ( in the sun ). It still looks brand new. I think J.C. Whitney carried it, but I believe Trailblazers or other speed or truck retail shops can order it.
 
i once filled the cracks w/hot glue..then sanded the curling edges of dash(i cut the majority of this off with razor knife) and the glue smooth, then painted the whole dash w/ black wrinkle finish paint b/c of the grain of the dash, no one ever noticed it, some friends got in and said, ''you finally got a new dash!'' they didn't know what i had done until i told them what i did, they actually thought it was a new dash. and it was a fairly good looking 84 2wd c-10 made for laying frame, had a 6/5 lowering kit. w/billet in the cab, so if it looked well enuff to go with ''bling'', you know it had to look decent.

my door panel tops started to turn to powder and became smooth, from arm riding there, i sanded the grain looking parts and wrinkle finished them in black also, looked good, but can't say how long, as i sold it @3-4 months later to fund my next project.

i have 1 dash pad, that i had an upholstery shop cover it w/ leather...iirc it was less than a $100, and looked good and was leather! it got sold in a project also!

i now have a dash that upholstery shop wrapped w/ red vinyl to match interior of truck it was in, it came from a you-pull it...iirc $15, maybe $25..i'm planning on dyeing it black and putting it in my k5, you can tell from dirt and stains,that it is old, but its still soft and subtle!

talk to some upostery shops, they can usually cover these in your choice of material and color...i want 1 covered in a mid/heavy weight rubber :-) and make sure my wires are waterproof w/marine style radio case and wet okole seat covers, that way i can spray the entire inside w/ water hose when it gets muddy!
 
i think ive heard the best idea yet. i thought about sanding the grain off but i didn't think of how i could "put it back on". does the wrinkle paint adhere good to vinyl? and the waterproof interior sounds great! what exactly though is a marine style radio case?
