there is nothing worse that stripping 50+years of paint off of a bike frame! i see alot of people using stripper to take it off, messy! on my bikes, i have started taking them to my local autoparts store that has a machine shop where they rebuild motors. they have a "hot" tank that they clean their engine blocks in and they do my frames also. i tell you what, for $10-$15bucks a frame, it is not worth the trouble to attempt your self! so you may want to research your town to see if you have a shop that would be willing to do this for you. it takes it down to metal, may have just a little sanding to do in the corners.
