I'm looking for options to flotation bags for a plastic boat.

Will the heat generated by pourable two-part flotation foam damage a plastic
boat?

What are the advantages/disadvantages to carving a block of minicell to fit
the boat.

Realize first I am as lazy as a cut cat.
What I have used when regular floatation bags are not available is a
car inner tube. Stuff it behind the seat and inflate it .
Cheap or free.
Some of the insulation foams i have messed with in my canoe actually
absorb water. They may not sink but do you want a 200 lb kayak.
As fot two part foams, I have no idea.
Good luck
