I haven’t stripped a P2K E unit, but I’ve had good luck with Easy-Off oven cleaner or Castrol Super Clean (the degreaser, not the concrete cleaner). Both will take off paint. However, both chemicals can give nasty chemical burns, so be careful with them. I use an old pair of pliers or tongs to hold parts while rinsing them off with water. Also, you’ll need some sort of plastic container to contain the liquid–an old Tupperware or similar container works great.
I don’t know about the Castrol product, but wear goggle type eye protection when using EZ Off or any oven cleaner. In fact, wear eye protection using any paint stripper. EZ Off is a strong alkali, so it dissolves the proteins in the wall of your eye. Alkali eye burns generally have a poor prognosis. In this regard, it is worse than getting in your eye (also not recommended). Other than that, Happy Modelling, Ken
91% alcohol works wonderfully. Let it sit sumberged for a while and when the lettering/numbering starts to lift a little you can take a soft bristel tooth brush and get most of the paint off easily. I usually let it soak after that for a little while and go back with a fine brush to get paint out of all the details. Good luck! [tup]
