Thanks for all the excellent suggestions, I am leaning towards the Duct Tape!! It is actually in a tricky spot, only accessible from underneath as there is a Arched plate on the inside that covers where the loose rivots are. Not very accessible from the inside.
Wow, that is very kind of you. I have the boat in storage up north right now but plan to bring it down to the city soon. I really appreciate your offer, and may take you up on it. I can get a compressor for sure. I take it you like your beer.... cold and wet??
Thanks again to all!
