Removing the paint from the Revell 1/12th scale Ferrari F2002

It probably has a tough lacquer on it that can be hard to get through.

Try Gunze (Mr Hobby)  Mr Paint Remover if you can get some or check DIY stores for a NON-CAUSTIC domestic paint stripper.   Failing that you could use an ordinary stripper but work VERY quickly with it getting it under a running tap before it can damage the plastic - a bit dodgy but it can work!

Contact Revell and see if you can determine what they used.

Automotive brake fluid will eat paint.

I've had this problem with some armor items I've painted.  I use the purple stuff from Walmart and have had to let it soak up to a week or longer.  Just check on it from time to time as it wou't hurt the plastic.  You can try the brake fluid approach like EasyMike suggested, as with everything try it on some scrap first.

EDIT: If you're going to leave it in the purple lake for a long time make sure you cover the container as it will evaporate.
