When you start talking about thin vacuform wraps, it's pretty hard to shoot the primer that thin. I tried Rustoleum on a scrap piece from the Apogee Saturn V wraps and if the coat was thick enough to be visible, the thin plastic started to distort... That's when I stopped using it... |

Use Tamiya Surface Primer on plastics. It is meant to prep plastic model parts for Tamiya lacquers. It has no fillers, since plastic models have fine surface detail. If you need to fill, then use a conventional primer/filler over the Tamiya.

+1. Tamiya Primer is great, dries quickly, but is pretty expensive. And comes in tiny 180ml bottles. It also goes on fairly light, which is great for promoting adhesion, but not ideal if you are trying to fill in and smooth surface imperfections. Quote:
I had bought a box (12 pack?) of Krylon Industrial Tough Coat Sandable Primer (aka KITC) once. It's great for larger surface areas that require a lot of sanding. But a 12-pack box is a bit of a commitment. I think I had ordered mine from Global Industrial: https://www.globalindustrial.com/p/...9RoCb5gQAvD_BwE The key is finding "Industrial Tough Coat" version of the Krylon primer, not the regular retail-store (crap) variety. If you want to try a single bottle for starters, those can be ordered from here: https://www.kljack.com/products/s00341/ -or- https://www.grainger.com/product/KR...le-Spray-54TJ04 HTH, a
