I've got several 40+ year old cylinders of which the epoxy coating has starting pealing off below the neck caused by the numerous hydro stamps. They're becoming rather gnarly looking and I was thinking about stripping off the entire coating. Is it safe to do a light sandblast job or will this destroy the galvanized steel surface. I bought these tanks new in 1973 and would like to give them a facelift.
