Painting white over red plastic

[Timonator]

I'm considering painting a kit that I have white. The problem is that the kit is molded in red. Any suggestions on a primer or basecoat that will work for this ?

Paint it black, or blue, or silver, then put a light gray primer over that. Then your white. There are many answers, but that's a good short one.

Ok, thanks

all u need to do is primer it gray

Seal it with future(pledge)  floor shine, gray duplicolor primer and paint.

I would use Tamiya fine white primer (no grays)  to maximize the brilliance of the white top coat.

Modern alternative.

I have used Tamiya Fine White Primer on both red and yellow molded plastic and never had any problems.

This has been gone over many times, and when I have to paint over a colored plastic body I spray Tamiya Leaf Silver on the plastic, followed by Tamiya White Primer, and then my color and clear coats of whatever brand of paint I wish to use. I have not experienced any bleed through using this method and it works for me. I only use gray primer if I'm painting the car silver or black, otherwise I use white primer.

My favorite is Duplicolor #1699 sealer or Tamiya silver....both work fine.

Thanks for all of the advice everyone .  I asked beacause I did the amt 70 1/2 motion camaro that was molded in green. I  used silver and tamiya white primer as base but the green still bled through the white areas.
