Yeah I guess I was the guilty dog about Awlgrip. I was using it as a reference, both being Interlux. No it's really not that picky of stuff, it's amazing paint that looks sweet, but is finicky in application. Whereas barrier coat is not. Mix it and spread it. A drunk could do it, and in fact I think it says on the can about the ratio of alcohol that should be mixed for the holder of the stick. Very important. Don't want a mans nerves shattered right in the middle of the job..
But yeah man. In all seriousness, you put three coats, (three gallons), on it and bottom paint that boat, with a LITTLE proper care you'll never do that job again. It is for sure insurance for the bottom. I'm not going to say you can't rub it off dragging the boat across 'Dead Mans Reef' a few times, but otherwise when your neighbors start talking blisters, you can just say the word 'barriercoat', wander off in peacefulness; because that is a pointless conversation after that point..
