i bought a 68 mustang that had a new dash that was still in the box but was the wrong color. The dash was 3-5 years old. i took it out of the packaging and cleaned it with soap and water and then with rubbing alcohol. i then let it dry and painted it black with SEM. i let it sit for several days before i even looked at it again but it appeared ok. several months went by and i had not installed the dash pad yet but went to install it when i noticed in several places the paint had sort of wrinkled and in a few places the paint had flaked.
what do i do wrong??
i then took some 1000 sandpaper and sanded the pad and cleaned it again with soap and water and the rubbing alcohol and painted it again and the paint after several days did the same thing. if i rubbed the dash real hard with my hand the paint would flake right off
A couple of details here. Firstly, which SEM paint/dye were you using? Was it interior paint or Vinyl Dye? Secondly, did you use vinyl prep prior to spraying the dye? Lastly, you're supposed to use laquer thinner and/or denatured alchohol as opposed to rubbing alcohol.

Bingo. I've done dashes and door panels successfully, but I cleaned the bejeezus out of them, with degreasers and solvents, scuffed off ALL the shine off with Scotchbright pads, THEN coated with prep spray, then color coat.

Scuff pads will work better than the sand paper and yeah, lacquer thinner might attack the pad if you soak it in the stuff. Fortunately, it evaporates quickly so if you just use a wetted rag and go at it, it should be fine. However, it may remove the old color so do with that as you will. Personally, I'd try to rub the old paint off the pad with the lacquer thinner before dying it again. Just watch that you're not wiping the grain out with it or something.

Rubbing alcohol has a little oil in it. Also SEM says use their prep so good idea to use their prep!
Molded parts like the dash pad often are coated with mold release. Very difficult to get it all off even without short cuts. We had production parts with special finish that had to be paint. Paint failure was usually because the supplier short cutted the cleaning process.

Unless I'm mistaken, SEM doesn't have an 'interior paint' vs a dye? I believe its all color coat, which is a flexible paint, which can be used to 'dye' interior parts. I dont' think they make a dye?
I have painted my door pannels, sale pannels, door sills, carpet on the pannels some other stuff in the interior with PPGs vinyl paint. Scuffed it washed it (simple green). Used non eviromental Brake clean to wipe it down before painting. Holding up fine cream before brown after

Read some of the vendors ads for it. They will as if you are painting hard plastic or flexible plastics.

OK, I just went to NPD's website. Could not find a different product for plastic or vinyl. I see your confusion!
Go to semproducts.com and read up on their different paints and what to use where. then contact a vendor.
I think it was American Muscle or Late Model Restoration I called when I was painting my console for my '95 when I got this info. They asked if it was the hard plastic or the soft armrest I was painting. SEM custom mixes paints for them.

If the paint isn't specifically marked as "Vinyl Paint" or "Vinyl Dye" (more common), I personally wouldn't risk it. Vinyl is way different than hard plastic.

What I mean is, SEM is called (by them) "a flexible permanent coating".. So it's not a dye persay, but a paint that you use on Vinyl.. ANd I THINK (this is where I was looking for correction), it's the same paint from them that you use on other interior parts.
So their Color Coat IS their interior dye, and interior paint, as 1 product.. Or at least, I hope it is, because that's what I'm doing!
