The Stovebolt Site Forums The Shop Area Paint and Body Shop Back side of rust area is inaccessible to sandblaster

I removed the rear fenders from my 53 Suburban. Broke 5 bolts off. There is a couple of areas rusted through. I intend on using an epoxy product called Duramix to place a new piece of sheetmetal over the entire area where fender bolts on. I figure this would prevent warping that would occur if using a wire feed welder. Problem is, I cannot access the area behind the rusted area with my sandblaster. Any ideas for preventing future problems behind this panel? Also, any ideas for removing broken bolts?
Thanks in advance to all you Stovebolters

if you can cut a groove with a dremal heat with a propane torch and remove with a screw driver or drill them out the metel seems soft i need to pull my back fenders also ill use air impact and snap them right off

Guess I'll add a Dremel tool to my list of toys (always wanted one). Thanks, I'll try the Dremel and torch idea. Any ideas for the rust repair?

Heat the bolts to a cherry red and they should back out.
