The short strain fiberglass doesnt use resin and glass sheets. its mixes just like body filler with harder. and space your tach welds out about 2-2 1/2" apart, and after you spot weld the metal all around every 2" thats gonna be plenty of welding, theres no way it would even think about coming out. also the differance between epoxy primer and primer surfacer is, primer surfacer fills and builds for sand scratches and other small inperfrections in your body work. also primer surfacer soaks up water like a spunge and holds water which is bad for running it on your truck for a while. expoxy primer is what you would spray over all the primer surfacer and body work. its more of a sealer than anything. also dont take off welding a bead on the sheetmetal, it will wrap the crap out of the metal and thats no fun getting stright if its even possible with average skills. also I wouldnt recommend using the body filler brand "bondo" after a while it shrinks and starts to crack, if you got the cash pick up some rage gold light weight body filler, cant ask for a better body filler. one more thing, be sure you grinf down all your welds so there a little low, always better to build up a sligh low spot.
