New engines and exhaust so i had to cut new holes for the exhaust. Going to be having some fiberglass work done in 2 yrs in the meantime i want to plug the old holes. The cutouts i have from the new holes are slightly larger than the old opening (3/16") so i can make it a very tight fit. What adhesive should i use? Was also planning to run some screws in from the bilge side.
any input appreciated.
