Paint removal on plastic models???

Easy Off Oven cleaner or Castrol Super Clean. Won't harm plastic, but Wear a mask when dipping or spraying the stuff.
Let it sit for about an hour or two, wash off with a old tooth brush.

 

Almost all solvents affect plastic negatively. Is it possible to just sand it down and reprime then respray?

 

Robbie's right, it takes a while but it's the best choice for the plastic.

I'd say the very last choice for paint removal on plastic would be any sort of abrasive paper. To get all the paint off it will remove detail, soften the edge of panels where you have to rub up to and along and edge, and the force of firmly holding the parts 'can' lead to breaks in screen pillars etc. And if your time is worth anything it has to be far cheaper to go and buy a new kit than sit down and carefully sand paint off all weekend.

The first thing I would try is brake fluid, this usually works. Immerse the parts in Dot 3 and when the surface starts to get soft stipple and drag it with a very stiff brush. This breaks the paints glossy surface and allows the fluid to get properly to work. Leave for a day or so or until all the paint has disolved off. It can make the plastic turn matt, but it won't damage it or soften it, although brake fluid should be kept well away from clear plastic windows etc.

If for some reason brake fluid doesn't work the second thing to try is oven cleaner, I guess in the US the 'Easy Off' that 88porsche944 suggested. This can work spectacularly well, or very poorly, depending on the paint and the application of the product. The key thing is to use it in a plastic bag so it doesn't dry out at all. If it dries it can set the paint harder than it was before!

Buy a new model and replace the messed up parts.

Seriously. I have tried paint remover and sanding paper and also trying to paint over. New parts is the best way to go.

 

You can actually just order replacement parts from Tamiya...should be under $10usd for a new body shell.

There is a phone number on www.tamiyausa.com


The number is 1-800-Tamiya-A (1-800-826-4922)

 

I've used CSC, it works great. Gloves and eye protection are essential.
