Foam Sealer

Can anyone provide the best foam type sealer to inject? between the fiberglass panels in the spider??? I looking for a product I can use to provide rigidity and soundproofing if possible. Merry Christmas to everyone.

Go with low expanding, I thought about this with my car but then chickened out due to possible damage.
X2 on the low expanding!
Another member here years ago used foam in the spider and doors, came back the next day to find them blown apart and warped terribly bad...
WOW, I need to do more research. The last thing I want to do is mess up the spider. Thank you for your valuable comments.
