Default Paint Removal Question

I have a Slot Car I would like to repaint, it has been painted twice. What is the best product to strip the paint and not eat the plastic. I believe I read somewhere on this site you could use Power Steering fluid. Is this correct?? I don't want to sand it off because you lose a lot of the bodies detail . Thanks Robert

Use alcohol the higher the ethanol content the better. I think most stores care 91% but I think I have seen 95 or 97%.
I tried the power steering and brake fluid. It made the plastic brittle.

I have tried methylated spirits on cars painted with Tamiya acrylic with some success, maybe I'll try isopropanol alcohol?

A friend of mine swears by DOT 3 brake fluid but I haven't tried this.

I have used a product call Testors ELO to remove model paints. It is water based and works well. The only problem is, I'm not sure they still make it. Try looking at Testors website.

The stripper that you might use would depend on the sort of paint that is on the car. Something that works well with solvent based paint might not work very well with water based paint. Another name for methylated spirits is denatured alcohol, which is usually ethanol with about 10% methyl alcohol.

I have stripped hundreds of cars. If that body has been painted from a rattle can - good luck. I think you will be using sandpaper, but I think your best bet is to use a rag wet with lacquer thinner.

Brake fluid will work, however, if you soak for too long it tends to make the plastic brittle.

I have stripped and painted hundreds and hundreds of cars. I strongly suggest that you not follow mayberryman's advice.

The water based, citrus, strippers will attack resin. On styrene, it may take a couple applications and an old toothbrush.

I've had good luck with soy-based strippers... they work well even on resin.

Actually that was a statement made by longdog, I was only warning of the propensity of the changing of the property of the plastic.

Only because Mayberryman has shown that he loves to correct my posts, allow me to point out that he is wrong, Longdog did not recommend Brake Fluid. This is what Longdog said and it is quite different from what mayberryman reported he said.

At any rate what is important here is that you not use brake fluid, there are other safe routes to take.
Good Luck with your project.
Jim

Thanks for pointing that out Jim, as you correctly said, I did not recommend using a method that I could not vouch for, I mentioned it in case others had tried it and could either recommend it or warn against it. Thanks for the warning against using brake fluid.

Castrol Super clean. I use it for miniature war models in plastic as well as stripping slot car bodies. Soak it over night , go over it with an old toothbrush. If any paint remains, leave it soaking for another 8 hours and repeat.

I once for got a body in it for a week and it was fine.

Just wear gloves as it will also strip the oils from your hand.
