Does anyone know where I can get something like J-B Aluminum Weld in Larger Quantities than in those tubes?
This ^What are you trying to achieve?
I have leak along the keel lap...What are you trying to achieve?
I'm trying patch a leak along my keel line...This ^
For sure there is an epoxy (and maybe a filler) to do the job, and it probably comes in every size up to 55 gallon drums
Does forever mean it fixes the leak or once you put it on or you can;t get it off...Depending on what you're trying to fix. another great option is 3M "5200" comes in tubes for caulking gun. It's extremely good stuff. Very impressive stuff. There's no going back once you use it though. it's "forever". lol. Comes in black or white.
