Raised plastic/resin pattern on my transformer. Faulty or removable? [resolved]

[Paul Birkeland]

I have used the VHT wrinkle plus paint a few times.  About one out of four times, I can get it to do the wrinkle thing properly, and that gets worse on vertical surfaces.

If you want to use truck bed liner, the Upol Raptor coating the best stuff that comes in a can by far, though it's expensive.

Good old Rustoleum 2x black will work just fine.

I've had pretty good luck with several light-medium coats in succession with a final medium heavy coat to get a good build usually giving a nice wrinkle. Kinda the same as building up hammered finish coats. IIRC a heat gun will accelerate the wrinkling. Bed liner is a good choice too. The ones I have used came out of the can with a lot of pressure and volume. Do make sure to drape off your work surface well.
