Simple lessons on why you don't fill body cavities with foam, underneath a vent that is sealed with a piece of rubber rope. Sadly, the German engineers at Volkswagen didn't know this in the 70's...
Keep cutting until you see no rust...not done yet!
You're going to need some holes from the inside to remove the foam...
I think we're almost there. Hey, the car is much lighter now!
Should probably check the other side...
Fun Saturday afternoon :P
