It turned out great! I dont know if the mods want to relocate this thread to the tutorial section but I will relay my experience below.
Prep! Mask off anywhere you dont want foam. I mean everywhere! Windows, upholstery, any metal bulkhead, heaters, dash board.
This is the most important recommendation:
For the ribs of the roof and below the windows, you want to cover them in clear packing tape. NOT masking tape. When the foam is cured (mine did pretty much instantly), you can pull on an edge of the packing tape and it will pull off the foam strip fairly easily in one piece to reveal the entire clean metal rib underneath. Super easy for post spray clean up.
Masking tape is not as strong and will tear far too easily and you have to chip the foam off. Its a lot more work.
Use an exacto knife/box cutter with the blade at full extension to shave off the overspray or areas that are thicker than your ribs.
You can see my bus in my build thread with the how the foam turned out. http://www.skoolie.net/forums/f11/lo...e-14005-5.html
