I'm curious about that weld thru primer, Do they have those in spaycans? [QUOTE]

Weld thru primer works great for most things, but stay away from SEM (and a few others)-they produce "spatter" welds-look for a spray that is high in zinc (which is what is in Weld-thru Primer), although as stated above I wouldn't use it anywhere other than flanges or rosette welded seams-
