Default what is the best way to remove old paint from a model?

Hello All.

Just finish getting all the parts of my old Airfix Eagle kit taken apart for a rebuild. but the old paint which has yellowed, was out of a testors spray can. what is the best way to remove all this old paint without destroying the plastic under it?
Any advice would be greatly appreciated.

Best Regards,
Chris

Modelstrip - a mixture of Plaster and Caustic Soda- plaster it on,put the parts into a freezer bag overnight, then rinse off, using a toothbrush to get into the corners.

oven cleaner worked for me on my Airfix Stingray - cheap as chips and available everywhere

got almost all of the paint off, the remnants were polished off with toothpaste

I've also used oven cleaner before. Just follow the warnings on the can. It's fairly nasty stuff, so you don't want to breathe the fumes or let it come into contact with any part of your body.

I tried easy off on a model of the ENTERPRISE I had and it only cause the paint to bubble but also turned the plastic gooey. had to toss the model in the trash.

Couldn't you have blown it up instead of trashing it?

If you haven't blown up a model then I'm afraid you haven't lived...

Soaking parts in brake fluid will definitely get that paint off!

but will brake fluid melt the plastic parts or make them brittle?

I don't think so. Ive cleaned up resin parts no problem but test it out on a scrap piece of spree first. Generally the brake fluid reservoir in your car is plastic too.

You could use plain old paint thinner. It won't attack styrene (like lacquer thinner will). I use aluminum baking pans (like the ones they sell to roast turkeys in) as a tub to do this in. You can also get plastic scrub brushes at a home store to help scrape the stuff off.

oven cleaner - it breaks down the vinyl component of enamel paint but not of the hard plastic of the model

I still had to polish with toothpaste to get the remnants of yellow and silver off

toothpaste is geat polish as its such a super-fine abrasive - I've been polishing clear acrylic with it and it gets fine scratches out but you have to rub really hard
