Stripping Resin?

+1 for the Mr. Muscle (non-caustic) oven cleaner, what we have in oz.

Left it overnight, no problemo. I use on plastics for enamels I didnt know if it was safe on resin, thanks peeps.

+1 to the Easy-Off oven cleaner. It works wonders. Follow the advice given, place the parts/figures in a plastic jar of some kind, soak with the cleaner, and the next day go to town with a toothbrush. Most of the paint will come off in the first swipe.

Castrol Super Clean (Big Purple Jug)  works wonders. But note, it will chew up any putty used on the model as well. Stubborn paint can be removed with a toothbrush.

Easy-off oven cleaner.   Put the resin parts in a large plastic or glass container, preferably one with a cover.    Spray the oven cleaner over the part getting good coverage.   Close the top and give it several hours to overnight to work.   Later remove and brush with an old toothbrush,   rinse and allow to dry.    Repeat as necessary.    Typical eye and skin cautions apply.

Others may recommend Simple Green cleaner.   Never used it having found success with the oven cleaner.
