Spot paint stripping plastic

I want to strip just the door from a TLT newsprint car. The doors are glued in and I can not separate them. I want them to be brown, and the factory yellow paint is much to thick to paint over it. Is there any gell type paint remover that can to a specific, masked area?

It would be quite difficult to do (IMO, not worth the effort).  But masking then sandblasting would probably work.  Do you have an air-eraser handy?

Most paint strippers for plastic are liquid. There used to be Chameleon Gel stripper but I'm not sure it is still being made. But even the gel was quite runny.

The whole product line is long gone. I was thinking about Easy Off, that foams up right?

I should invest in a media blaster.

It is a liquid which does foam up but then the foam collapses back ... into liquid.  Way before it had a chance to actually soften the paint.

I did this very thing using a Badger Hobby Sandblaster. I had a CN SD40-2w with sergeant stripes that I had to remove to paint the back end white (converting to an Expo 86 unit). I masked off the factory paint and then stripped the back end down below the roof line. Washed, remasked, painted, done.

Now that I have this tool I will never buy chemical strippers again.

Third the vote on the air eraser.  Used it on my polar express when some capillary action drew the spray paint into  some rivet areas along the roof. Media was aluminum oxide with no damage whatsoever.  It's very controllable but if you want to protect surrounding areas, I imagine taping it off would be good.
