What is your frame made of? If it's welded or even lugged steel, almost any paint stripper should be compatible. If it's aluminum read the stripper's lable carefully. Many paint strippers contain caustic soda (sodium hydroxide) which will badly corrode aluminum. Welded aluminum is safe with a stripper based on a chlorinated solvent (methylene chloride for example) but a bonded Al frame shouldn't be stripped with these. For Ti, which is sometimes painted, the sky is the limit. For carbon, absolutely no stripper is safe.
