I've got some RustOleum metallic blue that I want to use on a build. I'm doing a two tone paint job, Blue over Silver. I had painted an entire body using Testors Silver enamel that had dried for a couple of weeks. I sprayed the blue right over the silver, masking the area I wanted to stay silver. I used 3 coats light and 2 medium coats. When I went to pull the tape off the blue paint came right along with it. It seems like the blue sweated between the silver and the blue, it was noticably wet between the two colors. I get the impression that maybe the silver doesn't work well as a "primer".

Question one: do I need to use a primer with this paint or can it be sprayed right on the plastic?

Question two: Is it a better idea to pime (if necessary) mask for just silver, spray silver, remove masking when ready, dry, mask for just blue, spray blue, un-mask dry? Seems like a lot of work but for the best results I'm willing.

This time I'll be doing plastic spoons a couple of ways first to see which works best...just looking for advice.

Any thoughts? Thanks!

i would primer, regardless of the situation it also sounds like you went heavy if it bled under the tape.

tip, spray the blue first then the silver

Always prime. Usually spray lighter colors first, but the Rustoluem may lift the Testors paint, so lownslow is right about doing the blue first in this case.

RustOleum takes longer to dry that your average paint. I don't know what it is, it just takes longer. Spray the blue first, and then put it in a dehydrator for a day, if you have one. If it is a resin body, then you will just have to let it sit for a week, maybe longer.

Im painting a 1970 Gitane Tour de France(a bicycle, its another one of my hobbies) with said paint, i started with clean bare metal, and sprayed the paint on without primer, heres what i got.

it does take a little bit ot dry, and let it sit for a day or so to let the smell go away.

Also make sure you shake the can really well so you get all the flakes off the bottom, or else youll just be spraying a flat paint.

Good luck, Jeff

On metal, spraying without primer is perhaps ok, but on plastic, you could craze the plastic. Always always use a primer.

Mixing brands of paint is like starting the evening out drinking wine and switching at some point to scotch. The results are not always what you want. So get that scenario out of the way before it happens.
