I have an evil solution to my bodywork woes. Aluminum. I have a big chunk rotted out of the rear quarter panel that i cut out and drenched in rust encapsulation paint. My idea to fix the patch is to just make a piece of aluminum and put it on with metal epoxy. See im painting my whole truck in bedliner so it doesnt have to be too perfect. what do you think? The piece will be about 1'x1' with overlapping edges.
You may want to test some bedliner stuff on the aluminum first. Aluminum needs special care and/or primers in order to get paint to stick to it for any length of time. Other than that, sounds great.
I did something similar but I soldered a piece of galvanized sheet metal over a rust hole. You could use heating duct or something a little thicker. It worked pretty good...as long as you get the metal real clean and use soldering flux on the 2 surfaces the solder will flow in and creat a very strong bond.

I still think I'd test some of the bedliner stuff on a scrap piece of aluminum. Unless you're not worried one way or the other about the stuff coming off your repair.
THe problem with using aluminum is that two unlike meatals mated together will rot away with in a few months. The aluminum will corrode all the way around where it meets the steel quarter panel. I would suggest buying a repair panel and MIG welding it in place with a good butt weld.
I have found, having a Chevy Blazer for a bit that Galvanized sheet like used for heating systems works great and does not corrode. I would use that over alum. hands down. And the local Home D carries it cheep.
