Interior paint





GJS
I'm sure if it wasn't 'right' they'd make it right or give you money back. SEM is a pretty good company. If it's hard plastics (even softer plastics) be best if you spray on some adhesion promoter first. SEM makes it ..Duplicolor has some too that's pretty cheap. Bulldog. Or even spray some clear PVC cleaner/solvent (not the glue) out of a gun. Always test before you do. But that'll help on adhesion. I would put a mist of primer over the adhesion promoter (to make sure there aren't any fisheyes), then the paint. Even if it's a mist of primer out of a spray can. There's probably been a dozen coats of armour-all on the interior plastics over the yrs, so fisheyes are a definite possibility if not a guarantee. A 'mist' of primer first usually mitigates that problem. Then go a little light on your first coat of interior paint. Let it dry a bit ..a little longer than you normally might, then come back with heavier follow-up coats. If you still get a fisheye or two, spray some paint onto a sheet of paper and daub a bit on the fisheye.
