I would use an orbital sander to smooth out the rough gelcoat. It will leave a smoother more uniform surface with no digs or gouges like you get with a grinder. Just my opinion.
Thanks, how was the aluminum on your transom? Mine was full of corrosion perforations. I skinned over it with a piece of 5052. I'm sure I'll have more questions when I get to the front of the boat, just doing the back so we can use it.
The original metal had corrosion perforations on the inside from the wet wood rotting inside. I cut a piece of aluminum sheet about 1/4" smaller than the transom troweled 3m 5200 on the transom and riveted and bolted my skin on. Just waiting for the 5200 to cure.
I just skinned over my transom with .060 thick 5052 aluminum sheet. I got it from a local welding shop. I've also used metal supermarket, there's one an hour from me.
Hi, all. I need some advice on repairing some corrosion perforations on the transom of the boat I'm going through. My thought is to get a piece of aluminum sheet and fit it over the old one, scuff them up and epoxy and rivet it together, then use marine sealant around the edge after the epoxy...
Man, this is just what I was looking for! I've got a 93 that someone tore the floor out of. Now I can visualize the layout for the new floor. Thanks for posting this!
