I actually told GunluvS14 where to buy it and exactly how to do it. I've been foaming cars since 2001. It's pretty easy once you get a feel for the material. Your rockers for instance, you just take the nozzle and start spraying in one hole until you see it start creeping by the adjacent hole. Pause and see how far it expands. Then go to the next open hole and start filling from there until it butts up against your last injection. Repeat until your car is full to the top with foam!
