I am using "Circa 1850" to strip paint off the outside of the front fenders and doors on my '69 Road Runner. It does not seem to be working very well and even after 4 applications and waiting 20 minutes before scrapping I am not down to bare metal. Has anyone heard of "Aircraft Paint Stripper" and would it do a better job?? Your comments and help would certainly be appreciated. TseTse Runner.
