Oh it can be done. It would require way too much work removing metal and would probably be to thin (comparable to a beer can) to with stand any type of impact.you can not get rid of the stamped warning... the metal is altered by the stamping process and is physically different than the surrounding metal... we fought this with anodizing on our race car parts, welds will also do this..
props for the hard work and the great polish job... certainly more than I could pull off
