If you guys are so concerned about the health issues. Lack the equipment to spray it (rolling and tipping is not a better way...its just a way of avoiding spraying) Then why not do all the prep work (or better yet let them take it from start to finish as the prep work can make or break the entire look of the new paint job)...and take it to a pro and let them shoot it for you? By the time you screw around working on this project, buying or renting tools, paying retail for the supplies (there is a 40% to 55% markup on some of these paints and supplies)….all you will have done is waste a lot of your time and money for a mediocre result.

Sit down, price the job out...materials (sandpaper/wax remover solvents/sanders to buy or rent/ Cartridge respirator/paint base/reducer/catalyst/a clean, well ventilated area to paint/a large high volume air compressor with good filtration system if you want to spray (hate to tell you but a little 5.6 CFM @90 lbs air compressor ain't going to cut it) etc...Etc... And the time...however long you think it's going to take...multiply that by 3-5. Be honest with yourself and you will quickly see that you could make out a lot better if you worked some OT on your job doing what you do best and pay a pro to paint your boat and let him do what he does best. It's not a question of whether you can do it or not...ask the question is this the smartest way of accomplishing my goal.
