About three months ago I came across an article about repairing a cracked dash and decided to give it a try. Please note that I did not use the same products that Daron Walker used but they were similar.
- First I removed my dash and took out all the gauges and switches.
- I used automotive paint prep solvent as my grease remover and thinner to clean the dash of all the over thirty years of whatever was on it.
- I used 80 grit sandpaper around the crack areas to try and level it as much as possible.
- I cleaned with prep solvent once again before filling the cracks with spray foam.
- After the foam has cured I used a utility knife and sandpaper to shape the foam to the dash contours.
- Next I mixed up the two part epoxy (what I used was purchased at Lowes and was for plastic applications.) and spread it out over the cracks. I should have purchased the larger amount as I barely had enough to cover the now foam filled cracks.
- After the epoxy has cured sand smooth starting with 80 and then 180, 240, 320 then 400 grit to get the final finish.
- Now it's time to spray the bed liner, after the first coat sand with 320 to level then the second coat.
- Get a vinyl paint and spray the dash to level out the color.
- Finally one light coat of the bed liner.
This was the way I did my dash and for the most part I am happy with the results.
The two links I have listed below are where I got the idea to do this all the credit goes to Daron Walker for coming up with the idea:
