The tank on my 1957 B31 was painted siver. With a load of catty on the tank base.
Fearing the worst I set too with paint stripper. I need not have worried. The chrome was still there under the paint with no accident damage. Why someone put catty on the base I dont know because it was perfect, it had certainly never been opened.
With new chrome and paint the tank looks as good as new now.
Go for it, get that paint off!
