The lower area of the drivers-side rear door on my sisters 95 Contour has a rusty crack in it that is starting to get longer and longer. Right now it's about 5 inches from left to right. It's very thin right now though, maybe only open like 1/8 of an inch.
Is there any auto body patches or something that's available? Should I just try using some auto body filler such as Bondo? I know a lot of people use Bondo to fill in dents and stuff, but now sure if it will work as well with an actual "crack" in the doors outer surface?
THANKS!:)
