Our pontoon boat has an upper sundeck which is carpeted. Whenever the sundeck canvas is off (to let it dry out) the birds sometimes pick at the carpet and have pulled several strands loose. My question is... are there any good carpet glue products that would allow me to glue the strands back down. Need something that can withstand the sun and washing. Not sure why they don't bother the rest of the carpet in the boat. Any suggestions would be appreciated.
