Re: cleaning of aluminum boat
We're getting a new Lund aluminum boat. All of the hull surfaces are painted.
The owner's manual says it's okay to use an automotive cleaner or wax (liquid or paste) on the paint, but to test for abrasiveness in an inconspicuous area first. This assumes the paint isn't so new that it hasn't cured yet, but that doesn't sound like it would be a problem in your case.
