Painting aluminum haul

[Chinook Chaser]

What's the best thing to use to clean the haul of my Islander before painting? Also with an aluminum is it even really necessary?

all painting is 90% prep and 10% paint.

Check out West Marine they have some good information on paints

I have heard you can't just use anything, some of the ablative paints have copper in them, which I believe damages the aluminum, also not sure if some are slightly acidic and can cause damage.  Do your research for sure, and I'd be asking a reputable marine shop to find out.  Maybe even call the boat manufacturer and get an opinion.

Getting ready to do some painting on my aluminum boat as well. Most paints require an etching primer for aluminum. Check out James Distributing. The have a paint for aluminum that doesnt need primer. Brush, roll or spray.

Is your boat in the water all the time, or is it a "Trailer Queen" that spends most of its time high and dry out of the water and on a trailer?

If it is a "Trailer Queen" then you can just sand it a bit, roughening the surface,  and paint it with Tractor Supply paint at $25 a gallon, the same paint you would paint a tractor with that sits outside in the weather all the time. If it sits in the water all season you should sand it or rough it up a bit in some other way and paint it with some west marine advised paint.

I painted my Islander which is a "trailer queen" with tractor paint 3 years ago, changing the 1985 coloring (breast fed baby poop brown) to the blue and white coloring of the 90ties and it has been holding up great for the last 4 years.

If you choose to use an etching primer,you will have to remove all the old paint and immediately after removing the paint on a section brushing or spraying the self etching primer on. That is because it must be on there before the aluminum oxidizes, which happens within minutes

Jamestown Distributors has a paint specially formulated for aluminum boats. Its called Total boat aluminum boat paint. No primer needed. That is what I'll probably use. Its not that expensive.

Thanks for all the info. I know what paint to use I am asking the best way to clean it before painting. I painted it 4 years ago but do not remember what I cleaned it with.

Again, Jamestown Dist. has all kind of cleaners. Give them a call. You'd be getting answers from a proffesional then that can recommend the right stuff.

If you know what paint you are using, most come with prep instructions.

And no I'm not a rep for Jamestown Distributors. Just a good company to deal with. West Marine is great too.

I will look at the can again but pretty sure it just says "clean the haul". I can give them a shout, I would like to scrub it next time we are in the 40's start getting her ready for painting in spring.

Ive decided to put off my main painting till next year, spent too much on the interior rebuild. I'm going to paint my transom only, with Sherwin Williams 646 epoxy. Prep for it is scuff lightly. Wash with denatured alcohol and paint immediately
