Paint removal

[Wing Nut]

I have a 1950's circa aluminum boat with a fair amount of paint on it that I would like to remove. Chemical removal is not an option.

My question is there anyone who uses Walnut shells to blast with locally?

Thanks in advance, BH

Try calling one of the auto body repair shops in your area. If they don't know, try asking for a phone number to one of their paint/product suppliers. Good luck.
