Not the most common, mine was only rusty on one side! Arches are probably the most common...or the floor where the bungs are...or the front jacking points....hell a Mk3 will rust anywhere!
seeing your handiwork has given me the confidence to tackle the rust bubbles on the drivers rear doors of my mk3! Any advice before i go nuts with the dremmel!
cheers dude....been to Halfrauds and stocked up on supplies this evening I really need to get some pictures taken and get em posted of the car, not to mention general work in progress!! Will keep you posted on how i get on!
That won't take too long to come back through I'm afraid. Never been a fan of filling over rust. Should have cut it out and welded a plate in.
