Well, now that the obvious isd stated...does anyone have any tips for putting rusted drums off? I sprayed the hell out of them, let them sit, then hammered them and nothing. Then I whipped out the handy MAP torch and heated them up and hammered on them....nothing. Any other tips? I sprayed them again and I I can't get them in a few more cycles then I'm just going to load them up and then let them sit over night.
