Aluminum boat owners - What are you going to use for Antifouling bottom paint?

I store my boat in the US so I could probably get mine done down there.
Is there a good product down there for a boat that spends most of the year on a trailer and is in the water no more than 2 weeks at a time?
 
Isn't there some.new stuff that is super slippery that you can just wipe off growth? So slippery your boat might slide off the bunks? It's not paint. I'll go fin the name.
 

This stuff. Interesting concept. I don't moor my boat, and I don't want it sliding off the bunks willy nilly either.
 
Hullmax.....Nasco marine? Saw it on Live2boat on Instagram.

Here's that little video clip:
 
OK honest question so don’t slaughter me….is bare aluminum that bad? I have a 2023 Duckworth that I have put in a marina from May 1 to October. When I pull it out I get it winterized which includes pressure washing the hull. I get that there will be some growth during that time in the water but does that warrant painting or are you talking about boats that essentially stay in the water year round? Again, honest question.
Cheers

When I worked on shellfish farms, none of our aluminum work boats were painted, as we didn’t want the toxins near the product. That said, we had a marine ways and a commercial pressure washer to keep the boats clean. Cleaning them on a trailer is a pain.

In the summer there can be a lot of growth in a month. If there’s a big barnacle set, your boat will be completely covered in a couple weeks. Sometimes if we left the boats too long we’d have to scrape them with a hoe, as even the pressure washer would fail. You’ll also never get back to a smooth hull without sanding, as the base of the barnacles are stubborn. That however was in a high growth area.

Adding the epoxy barrier coat required before bottom paint is an effective way to electrically isolate your boat from stray currents in the marina. I’ve never been that worried about preventing growth, but preventing galvanic corrosion is a priority.
