Building an A4 clone and have a good A2 stock that we painted krylon tan years ago.
Need to get it back to plain black plastic. Best way to strip the paint without damaging the finish? Brake cleaner? Thanks in advance.... |

Citristrip. I've used it on many plastic and bakelite AK mags. Removed the paint and left the original ink stamps beneath intact. And it even smells good. |

Easy! The best product to use to remove paint from plastic without damaging the plastic WHATSOEVER is oven cleaner! Believe it or not... just spray the part, put it in a plastic bag to slow down evaporation and come back the next morning and rinse to an original finish.
One caution: I don’t know how it deals with any kind of acid-etch primer because that stuff bites into the plastic. Also, I don’t know what it does to anodized parts. |

Put the part in a big ziploc bag and pour in the goop. You don't need to fill the bag; just put enough in so that you can let most of the air out of the bag, seal and then spread the gel to coat the part. Leave overnight or for however long it takes, the paint will come off. Warmth seems to help the process, BTW. |
| Try Citristrip first. If it doesn't finish the job, KleenStrip MEK will work and you can let it soak about 5-10 minutes without damaging the plastic. Just wash it off with hot water thoroughly and make sure you wear MEK rated gloves and eye pro. (And long sleeves!) |

+1 on this - I've used citrus-based stripping gel many times with no ill effects. It's the pale orange stuff they have at Home Depot, Lowes or wherever. Put the part in a big ziploc bag and pour in the goop. You don't need to fill the bag; just put enough in so that you can let most of the air out of the bag, seal and then spread the gel to coat the part. Leave overnight or for however long it takes, the paint will come off. Warmth seems to help the process, BTW. The white lettering on the upper, rail, and optic is intact, but has taken on a light brown/copper colored tint to it. I don’t know if that’s from the paint stripper of from the paint itself. |
