I rolled and tipped my whole boat with Sterling paint 8years ago very similar to Awlgrip and it came out very good.
I also heard a story from a friend of mine who lost his friend by spraying a 2 part paint in his garage With Out a full suit on and With Out a air hose connection.
This is one of the main reasons why I rolled and tipped my boat Outside in open air.
I only used a cheep charcoal face mask and had no problems. The way I understand it is that both the vapor of the paint and the overspray after it is inhaled and dries inside your lungs is the problem.
I feel that the roll and tip method gives very good results, can be done safely by some one with no experience, cheaper that any other way to go, and even if you totally screw up your last coat all you have to do is pull out some more wet sandpaper fix your mistakes and add a additional coat and your there.
I am in the process of re painting my boat after 8 years I have collected some dings and scrapes along the way and I need to apply one additional coat of paint to cover up all these minor problems. The paint itself, that have not been damaged my general use still looks like new but you cant paint just a part of the boat with out seeing tough up stuff so doing one coat is the best way to go and is just a matter of cleaning her up wet sanding the boat and roll and tip one coat.
One thing to remember is to Pick You Days to paint, if you paint outside you need a day that has clear skies, dry, and not to much wind or you need a good morning to paint and then put your boat in a garage after painting if you dont you will be doing the job again.
