I have a 1979 Pontiac Phoenix with a console vinyl armrest that needs repainted.
The problem I am having is that the interior paint keeps crazing/cracking over time say 1 year.
First I cleaned it well with SEM Soap and vinyl prep.
Then I stripped the armrest of all paint which was quite thick from the upholster who redid it 2 times.
I tried a vinyl sealer, let it dry then sanded it with 600 sandpaper per the instructions, blew off, and then top coated it with SEM Color Coat. When the color coat dried, it came out very rough, almost like a sandpaper..
What I saw under a magnifying glass was a lot of very very small pinhole bubbles in the color coat, with some larger ones, say 1/32 diameter.
SO being the experimenter I am.
I am planning on using SPI Epoxy to seal it, I've previous used it to seal metal items I've painted.
I plan to restrip it back down to good vinyl, which is still very nice and supple and no cracks.
Then use Bulldog adhesion promoter, 1st coat light wait 5 minutes, then second light coat.
Then. wait 1 hour and then use thinned SPI epoxy to seal.
The wait 2 hours and then topcoat with a few light coats of SEM Color Coat, just enough to cover...
Questions:
1. What do you think of my wait times??
2. How much should I thin the SPI epoxy??
3. Other suggestions??
