Aircraftresourcecenter.com - Stripping paint I've used Easy Off Oven Cleaner (from Ace hardware) with great success to remove paint from a 13-year old 1/32 F-14.
However, I don't encourage to use it if you only have a few small items to remove paint from. It's pretty bad for health and you gotta make sure you do it outdoors. Also need rubber gloves as well cuz the stuff burns...
