How do you do it?
Properly paint an aluminium hull both above and below the water line.
I have to start this weekend. I've heard several different ideas, but no one seems to really know the best way to proceed.
I want to strip off as much old paint as possible, Prime and repaint. I have 2 gal of DEXTER 2 part petroleum resistant aluminium aircraft primer and
2 part Imron top coat paint. Will this work OK for above the water line and is an "etching primer" necessary? Would appreciate any info
from experienced boaters.

Well, I'm not a professional boat painter but I think you'll have to take the boat out of the water to paint below the waterline.

Believe it or not
There is a bottom paint that can be applied with the boat in the water.

I have an old aluminum boat
I have painted it several times in the past 40 years and I will tell you not to waste your time if you don't first etch the aluminum after you
have stripped off the old paint. You can etch the aluminum with brick cleaning acid. This both cleans it and etches it. I suggest that you first
invest in a good pair of rubber kitchen gloves and a pair of goggles or a face shield before you handle the acid.

One thing make sure you don't do is after you have used acid wash --DO NOT Touch WITH YOUR HANDS--- not just because of the acid but your body
has oil in it and any place you would touch with body oils will cause you to have adhesion problems. also make sure to use air to blow all acid and
cleaners from cracks and rivits ! the primer and paint your are going to use will stick to anything it drifts to so make sure everything is covered ,
hard to get primer and paint to stick to what you want it to but for some reason it will stick very well to anything you don't want it to.

As far as preping it they actually make a primer that etches it.

Thank's Guys. I will be painting above the water line for now. I will do the boat in sections roof, sides deck, etc. This will limit the mess and
allow time for paint to set up before evening.
I'll pull the boat next year for the bottom.

Beware
If your are doing this on the water at the dock none of the products you are using are environmentaly friendly.You might get stopped in the middle of
the job, and imron paint and primer has a very strong smell !

Gonna do it right!
I use a vaccume system orbital sander. The canaster's filter bag gets packaged and disposed of for free at a recycling center in Dayton. When I
paint I do not spray. I roll on both the primer and 2-part polyurathane top coat will a leveling agent and special rollers. You get a great finish
with out the hazards created from spraying. When I'm finished all materials including brushs, disposable tarp, rollers, etc is boxed up and taken
to the recycling center. I plan on doing the boat in sections makes for a more enjoyable project and keeps the neighbors happy. I work clean and
don't leave any mess period. My docks always clean. I have never had a negative comment from my neighbors and always paint in the off season.
Warm dry days are best. Paint sets up quickly. As for smell, etc you would have to come on board to notice.
