When I first got my boat I did a leak test and found a few missing rivets. Fixed and sealed them. Took it out yesterday on a local lake and over 2 hours on the water the bilge pumped out maybe 5 gallons of water.
So I did a leak test again. Found a bunch more leaking rivets and several missing rivets. Fixed those and had a ton of coat-it epoxy left over, I'd mixed up the whole quart thinking I'd need more than I did. So I spent all evening laying on my back under the trailer coating every rivet head I could find until my wrist was sore, the epoxy was setting up to the consistency of bread dough, and then I finally ran out.
