I have a 40 year old boat I want to make just a bit shiner. Old water lines and dull. Any suggestions? 14' fishing boat with no paint.

if you have a drill and buffer pad for it you can get a product called (Never Dull) it a cotton wading just tear off some and put it on you pad and start polishing, you will have to buff it by hand when you get a film kind of like wax, this stuff is good, might take 3 or 4 cans to do your boat, after you get it back shiny you will need to seal it so corrosion won't start again. Then grab a six pack and go show it off

Try an automotive aluminum wheel spray-on cleaner.

Use Alumiprep rite out of the jug and let set on hull fer 'bout 3-5 minutes keeping it wet then rinse off and buff with aluminum polish....use rubber gloves wit Alumiprep and scrub brush to stirrup and keep wet.
