    Okay so I am trying to strip the paint off a resin figure (revoltech like plastic) and when I did a test piece in lacquer thinner it worked! took the paint right off! but it made the plastic soft........so that's a no go, next I tired some alcohol 70% and that just isn't strong enough.

    so my question is can you guy recommend something that will take it off but not make the plastic soft?

    Try 91% Isopropyl Alcohol with an old yet good toothbrush!

    NO. Most emphatically no. Don't use acetone! It disolves plastic (this is why it works on superglue. Cyanoacrylite contains acrylic, which is plastics).

    The paints on almost all toys are acrylic pants which were in an alcohol medium, in order to cry really fast during assemly. As such, using alcohol with a toothbrush or even a cloth will remove it fairly easily in almost all cases, since you're basically re-disolving the paint particles.

    Thanks so much guys! Saved me from messing up another test part lol...........my last question is if I am using 70% Alcohol now, and it's NOT working, when I use a stronger 91% how long do I leave it sitting submerged?

    I think it depends. Some plastic and paint are simply stronger and more durable than others. It's better to err on the side of caution though. I'd say just supervise it.

    You can try nail polish remover, but just be warned that it contains acetone and can damage (or even melt) your pieces! When I've used nail polish remover, I use Q-tips and I have a reservoir of water near me. When trying to remove paint with chemicals, just remember to be conservative about it. Time and elbow grease can sometimes be better than having to get a replacement piece only to start over.

    My question is do I NEED to get the Paint off? Or can I get primer over it and then paint........The reason I want all the paint off is I found "rubbing" problems before so I figued if I got all the paint off it would work best.......but then again people say you cant get away from rubbing anyways

    It's hard to say, but I'd think that if your problem is paint rubbing, you'd be better served by removing that layer of paint, and prepping/repainting to resolve the chipping issue.

    By principle, every time you paint a coat of paint on, you're adding to the piece's thickness.

    You can always sand a part down some, and then paint it to prevent rubbing/chipping some :)

    You can always dilute a solution with some water.

    Tried to dilute it with water even at 50/50 it "melted" the test plastic........So I wont be going the acetone route at all, I don't want to sand the whole thing so I will just soak it in Alcohol 91% for a while and clean it really good with a brillo pad and Prime it, paint it, seal it..............I cant see another route at this point

    Nail polish remover < acetone (by itself)

    Nail polish remover is diluted acetone.

    For your figure, you may just be better off painting over it.

    OK...do you want to know an OLD modelers secret? Get rid of the acetone...the alchol and the thinner.....Most of those will damage the plastic if left on to long.
    Go buy a can of unscented EASY OFF OVEN CLEANER....yep that's right oven cleaner. Spray the part heavily with the oven cleaner....wait about 3 to 4 hrs and then under warm running water use a old tooth brush and gently brush the paint off. Works every time. AND it will not damage the underlying plastic. I have been using this technique for almost 15yrs now.....it has saved me from having to buy a new model because of a crappy paint job many times. Let me know if you have any questions on this. Good luck with your project.

    a degreaser like the oven cleaner mentioned, though the dollar stores have something called "orange stuff" or something like that. Recommended to me for tree sap. Works but needs elbow grease.

    When using the oven cleaner make sure your in a ventilated area and you have gloves on.
