So I've got a k11 and I've noticed a bit of rust on my sill. The rust patch is no bigger than 3 x 2 inches and it's on the rear of the left hand side of the car. My question is how much would it cost in a garage? I would normally do the work myself but I don't have a welder and the fact that I've never welded before. Also has anyone bought the sills from ebay( the cheap ones), would they be good to use? Any help would be appreciated.
