I was going to start another thread for my OB product test of the almighty Flex Seal but this thread will do. I have a very leaky aluminum boat. All the rivets leak and I also had a small hole about the size of pencil lead.
I started off by wire wheeling all the rivets
Then I sprayed flex seal around all the rivets and used JB weld on the small hole
I then coated the entire bottom with roll on bed liner that can be bought from autozone or Wally world.
I'm very satisfied with the finished product. The boat no longer leaks and it looks great. Before I would have to run the bilge every 15 minutes or I would sink. Now no water.
