I'm sure you know the mess that was in there already.
My biggest concern is insulation, but adhesion is a real close second place ... maybe even a tie!
I'll be looking to place an order.
You're welcome. Glad I could help! There are other brands of two-part closed cell foam kits, but I am very partial to Touch 'n Seal. They cater to do-it-yourselfers and have produced several youtube vids to help people out. They will also talk with you on the phone if you need help/have questions.
FYI, spray foam insulation is measured by the board foot, which is 12" x 12" x 1" thick. I would put at least 3" in any roof/cap area, and more is better. That means that an 8' x 3' cap area would need 72 board feet, and you should allow 10% extra for overspray/waste.
Touch 'n Seal makes a 200 board foot kit and a 600 board foot kit. If you get the 600 board foot kit, you can use the leftover material to insulate your bus floor from the underside - an amazing comfort upgrade regardless of the climate you're in.
I should probably become a dealer for the stuff...!
BTW, for anyone else reading this, I only recommend the kits for small jobs like the one Tedd is working on. If you're insulating an entire skoolie, it will be more economical to have a pro spray it for you.
