hacked the rears


Recommended Posts

Water absorption is dependent on the type of foam. There is open cell and closed cell foam. The closed cell will not absorb water. Most urethane foams are closed cell. Whereas a sponge is open cell. The test to determine which kind you have is easy. Put a sample of the foam into water and watch what happens. It should just float with no change is water level.

The other great thing about typical insulating foams like 'Great Stuff' is it has great adhesion especially to rust and steel, so it actually can seal against moisture penetration. It's great for body rust repair.
