Man, I live having a paint expert on site! I feel like I'm cheating every time Downriver answers a question. It's not supposed to be this easy.
Now for my next question.
I use PVC as a lure body material.
I prime with Krylon white primer, rattle can, thin coat.
Then I base coat with Createx new Wicked Color white, and do my other colors over that.
Usually they are a mix of Auto Air, Wildlife, Createx, and Apple Barrel.
I heat set each coat with a hair dryer, first on low, until the gloss/wet look is gone, and then on high for another ten seconds per section.
I usually mix in a coat of Krylon fixative over my scale coat, in case I screw up the next color coat, so I don't have to redo the scales, and I use a hair dryer to dry that, too.
Finally, I use either Krylon spray glitter, or Minwax Polyacrylic with fine glitter to add the last coat, hit it with the hair dryer, and let it hang overnight.
I coat the next day with Nu Lustre.
My question is, do any of the intermediate layers provide some kind of protection for the Createx, since you say it sets at 325f, and I'm sure I don't reach that temp.?
Sorry to be so long winded.
