If you go with a sealer and it doesnt work.Your gonna give the guy that will try welding it up a nightmare Hence why i said TRY.Hes gonna fight welding it up with that crap contaminating the weld.It'll go something like weld grind weld grind weld grind pressure test weld grind pressure test weld grind.Add a sealer you can turn a 5 min weld repair into a whole days job
