Paint

Don Thompson recalls that the Chinese factory used automotive paints on their freight cars. All plastic bodies were made out of ABS.

Brian Jackson reports that he has had success removing paint from a composite hopper using 91% isopropyl alcohol (IPA). He reported that he started seeing results in a few minutes, and large amounts of paint came off after about 30 minutes of soaking.

Jim Kindraka adds to Brian's report by saying that he'll put a paper towel soaked in IPA over a car's side (so as to reduce the amount of alcohol needed), and just keeps it moist for several hours. After that, he uses a toothbrush to remove the more stubborn areas.
