Sharkhide or ceramic coat on new aluminum boat

[the butcher]

Has anyone used sharkhide or ceramic coating on a new aluminum boats paint and hull? The hull is bare aluminum while above waterline is painted like most aluminum boat manufacturers. Wondering if anyone can share their experience. Thanks

Never heard of this product as a protectant fornaluninum boats. The brief research I did comes back with this product being a protectant for fiberglass. See nothing about aluminum. Are you using this as a bottom paint for your aluminum boat?

I did forget to mention my aluminum boat is on a trailer so I am not looking for an antifouling bottom paint.

I want to protect the bare aluminum hull and rest of boat that is painted aluminum.

yes i use it as a bottom and top coat. its got excellent adhesion to bare aluminum.

it forms epoxy microplates completely isolating the hull.
its not an antifoul - you would need to do an extra bottom paint over it if you wanted antifouling - but you dont need antifoul paint on the trailer obviously.

dont use interprotect above the waterline, I swear sometimes your just trying to dick people around? It’s an epoxy primer they have no UV protection not something you want to use on your hull sides.

Nyalic, sharkhyde, wrap or a full acid wash and conversion coating above the waterline.

Big fan of sharkhide. You will need to reapply on areas with heavy wear. Be thorough and wipe nice and evenly. Make sure the aluminum is DRY. A leaf blower is useful. If you apply it over water drops, you will not like the finished look. Less is more and try not to overlap too much. Don’t add the second coat until the first is 100% dry.

Sound advise above.

If you miss a spot, don't try and touch it up 30 seconds later. Wait till it's all dry and get it on the next coat. You must do a couple coats minimum. It's tough to see where you have already made a pass.

One drop will screw up a big area as noted (just esthetics).

Give the boat a good wash ahead of time. I like to let mine air dry through the middle of a sunny day, then apply the coats once the suns off of it and any spec of water hiding under a window frame etc is gone.

I've used it for 4 years and it works. High traffic areas like where the bumpers rubs will wear it off in a week.

The sharkhide crew tried to convince me to put in on the checkerplate. Happy I didn't do that.

I applied Nyalic to my new build aluminum boat a few years ago and it's done a fantastic job of keeping it looking like new and avoiding oxidization, the cost and application time is very minimal on new aluminum and seems like a no brainer for a new boat. I didn't apply it on my gunnels or deck but all other areas and its held up very well after a few years with no maintenance, I'm located on the South Island if you wanted to come take a look the different surfaces and outcomes prior to applying.
