Can u replace the cowling foam with undercoating

[salmonslammer]

The insulating foam on the inside of my cowling is crap....I ripped it all out before I start suckin it down the carb.

I was wondering if I can put 4 or 5 coats of undercoating on it and call it a day....

or do the put foam in there for a reason?

I think it's main purpose is as a sound deadner.

tore mine off also....also blew into the carb vacumn hose....something was blocking it.. ... suspect that foam....boaters world has replacment stuff that looks pretty good.

Thanks....Ill check into it.

Stupid thing is louder than hell without the cowling on...Id imagine the foam helps quite a bit. Ill run it next week and see if its tolerable...

Foam is used for sound deadening.
