Hey guys, Mikiec is absoultely correct. The foam does expand and during the MKi and MKII years there were a lot of stories about guys who had used the foam and it had expanded and did some cracking of the fiberglass. The use of the grey hot water pipe insullation from Lowes or Home Depot is possibly the best idea. Don't try to install it while laying on the ground and pushing it up between the body and frame area. Find a friend with a lift and get the car in the air, you will find that the installation is redicalously (sic) easy. Also, once the car is in the air you'll be able to better understand and see what you are trying to fix.
