For those of you that used SEM, did you prep with the Sand Free or the Plastic Adhesion Promoter?
Sorry for the late reply, @Camhabib , but yes, I bought and used the entire prep kit: SEM Soap, Sand Free, and the Plastic & Leather Prep. There are specific instructions on how to use all 3 of these before painting. It takes time and adds to your total cost significantly, but they say this is how you get the best results.
To @alexap 's comment about longevity, I will say that the low-contact surfaces have been a 100% success: dashboard and console. Again, the color is dead-on and nobody would know that these surfaces were painted — they look like new and have held up very well so far. Medium-contact surfaces like the door panels have been mostly a success, with just a bit of peeling on the top. In my case, I am painting them the original color, so peeling isn't noticable as compared to @intheSFValley 's project. But for high-contact surfaces like the armrest, the SEM paint was a total failure. I don't know if it was the material the armrest is made out of (vinyl?) but the adhesion was poor and after just a couple weeks of driving, the paint was peeling off that surface pretty badly. I ended up just rubbing off all the paint from it and leaving it original. If it were a big problem, I would just buy one of the armrest covers they sell on Amazon.
