Painting aluminum for salt or fresh water immersion is not recommended. Most boats in Alaska are aluminum and are not coated. If painting is necessary, Awlgrip is likely yours best bet as it is meant for immersion and has an excellent mandrel bend which is needed on flexible metal.

I was thinking the same thing. Funny how they make absolutely no claims about how long the product lasts, isn't it?

I have never seen the hull of an aluminum boat painted where the coating held up. Below the water line should not be painted. Awlgrip hull guard is not recommended for aluminum below the water line. The data specs exclude aluminum. There is no coating that will work for any reasonable service life. Just paint at the water line and topside.

Some other questions come to mind, who's idea is it to paint the thing in the first place, and do they know what they are talking about?

Is the paint job purely for cosmetic decoration? Or is the purpose to protect and extend the life of the vessel?

I assumed the boats were for a rental company. The rental place here has all there boats, canoes and kayaks a safety orange color. Maybe not the hulls but enough where you cant miss them in the water.

The Hull Guard Extra is specified for aluminum.

Thanks NACE You are correct except you failed to mention that Hull Guard Extra is step 2 of a 6 part system to coat below water aluminum. Now I ask who in their right mind would do that.......Even a 10 million dollar aluminum tuna boat built by JM Martinac is left uncoated. Now back to the orig. post I bet its a couple swamp boats they want to paint. I forgot about the government they would spend that money.

I would contact a marina or a boat supplier for more info and to be safe. Kinda a big investment to screw things up and I'm sure much harder to fix if it is done wrong.

Good luck to you.

Yes, my original post recommended not painting it. However, just recommending a system that could work but the budget and effort are up to the people writing the check I guess.

Etch and anodize it. I used to work for a plating company years ago. But I never saw anything as large as a boat.

It's always about the money . People want things painted but never want to pay the price.......NACE I have been reading your posts a long time you know your stuff. I hope you don't think I was trying to correct you. I know there is always another way or option to paint things. I bet we wasted our time talking about it ,the orig. poster has not chimed in so it's most likely a couple of row boats. Nothing of much value.

He probably got a couple cans of rustoleum spray paint like they all do when they see how expensive the correct paint and procedure is. $200.00 is a lot of money for a fishing boat to some people. $50.00 a quart and 6 steps to paint it? No way!

But if he had just bought the rustoleum boat paint I recommended, at least he would have bought something with a picture of a boat on the can.

No problem. Always try to provide the best info that is honest and unbiased to help with understanding what is the best approach without considering budget. Budget is up to the customer and the chosen applicator and their respective expectations. Money is always the issue. I want to insure the best possible system and sell the reason why the customer should choose us and why they need the best. If I hadn't made so many mistakes in the painting industry I wouldn't know so much!
