Unless that is pink primer, I would say the color from the plastic has bled through the primer. I would say you need a better primer, primer sealer, or try using silver paint as a sealer. Then color coat.  But others here might have better advice.

I had a similar issue with my Revell Porsche slantnose.  It was red plastic, and I was originally going to paint it pearl white, but the plastic bled through.  Came out a pretty pearl pink when I was done.  :)

Brain,

I decided to just Clearcoat as is. I can't decide if I hate it or love it. The kit does have a lot of chrome parts, and they may help with the overall look.

Red bleed-through has been discussed ad nauseum for years.

There are opposing "opinions", some insisting it's real, some saying it's not.

SO...I did my own tests.

ALL red plastics DON'T bleed color, but SOME DO.

Shooting silver over the primer is the best way I've found to block it under light colors so far, without excessive film build.

It's really not an issue under reds or dark colors.

That statement sounds contradictory to me.   How can some (red?) plastic kits bleed colors while all red plastic kits don't?

Think about it.

If I'd said "no red plastic kits bleed" but "some do" it would be contradictory.

Remember that part of the argument out there is that "all red plastic kits bleed"...but the truth is that ALL do NOT bleed...only SOME.

My sentence construction possibly isn't the best to convey that idea, but it's still grammatically and logically correct.

EDIT: It would admittedly be more clear had I relocated the word "not" to the beginning of the phrase, making it "not all red plastic kits bleed..."

So sue me.   :P

To further this along,,

I've also had orange and yellow bleed but never had blue or green do it. Anyone else have any experience with this?

The reason most silver and gold paint will block it [I'm pretty sure based on my 40 years experience being a painter] is they have flakes as the main pigment that lay down like shingles on a roof and form more of a shield then other colors where the pigment is usually more round particles, more like balls in a ball pit, allowing the dye to easily come up through.

Shellac works in the same way, made up of flakes in a liquid carrier, when dry it forms a sheet sealing in stains, dyes etc.

Yes, I have found the very same.

the worst bleed through i've had was the orange revell t2. with every coat of grey primer it got more and more peach and it took 2 coats of silver. usually just enough to cover does the job but it took a paintjob nearly. if i wasn't just using the tailgate it would have made a great early 90s cal looker colour

Well with English being my second language, maybe I chose the wrong word. Maybe I should have used "ambiguous", "confusing" or just "doesn't making sense" would have been better than "contradictory".  As I understand it, the first part of the sentence was contradicting the second part.  If *ALL* red plastic *DON'T* bleed color, how can "SOME* bleed?  "All" excludes any exceptions.   Illogical!

So sue me. :P

Mike you can always go with Red and I like the Red pepper in Krylon short cut at hobby lobby.  You could grey primer it and clear the grey primer

Thing is, I probably wouldn't lecture YOU on YOUR first language, but that's just me.  ;)

I don't know if I am going to love it or hate it. I am just going to Clearcoat it. It will be a unique color. I think that that with all of the chrome parts it will help with the overall look.

I don’t quite understand the original question? “Is the primer still on the plastic to protect it from a hot paint?” I gather that the kit is probably molded in red and that is just white primer…hence the thread title? Now you are just going to clear coat over the primer with no paint? The primer will still serve its intended purpose of promoting paint adhesion (and protection from a hotter paint) even though it has turned pink. Any dark color paint should hide the red. Like mentioned previously though, a coat of silver should hide it for lighter shades of paint.
