I have a small crack on my boat and it had been repaired with 650K epoxy and fiber tape. The patch was on the boat when my wife's brother bought the boat. So I know it was at least 5 years old and it did not leak. Kind of sitting on the fence on making repair. Weld or go back with same patch? By trade a Tig Welder. Everything from military planes to military ships. Over 20 years experience. Knowing how old aluminum sometimes does not work out as planned I am not sure which route to take. After reading your post kind of thinking about welding the crack.</p></blockquote><p></p>
