Great job,thanks for sharing.

The only thing I do different is I add some denser foam into the core area (I cut out the center (use a bread knife) and form a plug out of the foam board) I like to use kids boogie boards (the eatha foam ones, not the white fome) and then cover and spray in the foam, shape  and paint. The inner foam stands up to 100s of shots or broad heads better than the spray foam alone (I purchase the boogie boards at flee markets, church sales $5 or less entire repair less than $15)
