I've seen these threads about adding flotation off and on for some time now.
An idea I've thought of but NOT TESTED is this: Get plastic trash bags (good
quality for heavier plastic) and open them up in the compartment you want to
be for flotation. Tape/glue them in place in an open configuration. Then use
the spray cans of foam to completely fill the compartment/bag (after
expansion has happened). Trim off any excess foam and close the bag with
tape/glue;
whatever works for you. The foam then won't stick to the hull/fiberglass and
would be easier to remove should that be necessary in the future.
