What Sealer Do You Prefer When Painting White on Red Styrene>

[impcon]

This is a question that has been asked before but it bears asking again based on personal preferences. Perhaps, this might be considered as a sticky because both new and seasoned model builders are almost always open to opinions and new ideas. So what sealer do YOU prefer and use when painting over a red body or body parts to stop the red from bleeding through. Someone suggested that the red colour doesn't "bleed" through white, because the white is opaque. I am not a paint specialist or chemist but I do know based on painting 1:1 vehicles, that a stop bleed product has to be applied over red. I am self taught with painting 1:1's and I learned a lot of lessons the difficult and costly way because we did not have the Internet back then to do research on. My first ( and only experience ) with white paint over red took place when I painted a GMC Astro highway tractor that was solid red and two toned it red and white. I finished painting the white, left the shop and returned several hours later to stare when I discovered that the shiny white enamel turned had turned a VERY effeminate shade of pink which is about the last thing that some macho, 265 pound, bearded, ornery truck driver appreciates or finds amusing. I mean, this guy loved his truck and seeing it in pink... ??? Needless to say, I had to let the truck sit and then seal and respray the white. The 1:1 Sherwin Williams product that I used to seal the red was a black coloured product appropriately called I believe, "Stop Bleed".

So what is your time tested favorite? Or have you found just a colour of paint that you can apply as a sealer? Inquiring minds need to know...

Mine is a silver or aluminum paint, as the aluminum in the paint will create a barrier the color can`t bleed through. I built a bunch of the 1/12 `67 Corvette kits, which are of course molded in red. I have tried sealers, high build primers, etc, and they have all bled through white once the clear coat was applied. Numerous times I had pink stinger stripes. Since using silver or aluminum paint though just before the color coats, I have had no issues with bleed through. I have one with a white stinger stripe that was built over a decade ago in my display case. The stinger stripe is still bright white.

Tamiya Silver Leaf, then white primer, then color coats and clear coats. Works for me.

I think we have a winner here folks

Any silver, black, or blue should work, followed by a light gray primer and then white primer or your white paint.

And again, the pigments in red styrene do not "bleed" out of the plastic and into the white paint (and I can prove it). The problem here is insufficiently opaque white paint, and it possibly also has something to do with the wavelength of red/orange color/light being able to penetrate white/light paints better than the wavelengths of other colors. You almost never hear anyone worried or complaining about blue, green, gray, or black plastic "bleeding" through white paint.

I spray a couple of coats of Plasti Kote gray sandable primer, allow it to dry well, then spray Plasti Kote white sandable primer over that. Then, paint and clear.

Tamiya Fine White Surface primer is my "go to". As it has worked for me, I haven't tried the other methods.
