i have a rust hole in my rear wheel-well and was wondering the best way to do that. ive got towels back there now and i really, really dont want my subs getting wet at all. any ideas??

 

How big? If it's small you could just cut out the rusted area and bondo it. If it's to big you'd have to weld in a P3 (patch, prime and paint)

 

its not very big... or so i doesnt look that big. its about the size of maybe a big cell phone (sorry for the bad comparison), so not huge.

 

Since it's inside the wheel well and not visible , pull the tire and take a piece of Aluminum and cut it to fit larger then the hole Drill several spots around it for pop rivits ... Apply silicone sealant around the patch ... Put it back up use the pop rivits to pull it in ... Then apply a coat of sealent from inside the trunk
