Sound proofing help

[Totally unexpected]

Wanting to sound proof the engine compartment in my boat,looking at dynamat,kilmat,noico. Any suggestions as for a good quality sound proofing that will hold up to marine environment? I'm leaning toward the kilmat,80mil,and then buying the separate dynamat doghouse kit.

The stuff trotac sells was of good quality
10 plus years on it and still looked like the day it was bought. Not sure of what the brand name is. About 3/4 inch thick or so Reflective silver skin on one side. Give them a call I’m sure they’re point ya in the right direction
