I loves me some Hydrocoat

I think I've mentioned this in a previous post, but I ran a Sherwin Williams aircraft paint distributorship
for 5 years back in the early 2000s. We sold a water-based paint, or rather we tried to sell a water-based paint because aircraft painters are a stuck-in-the-mud lot and are petrified to try anything new for fear it will upset the paint fairies and leave them with blushes or blisters and a corporate jet repaint bill of $250K. In addition, after painting with 2-part polyurethanes for decades, they found it impossible to believe that any water-based paint could stick as well as their urethanes or look as pretty. It became necessary for me to send out samples to painters just so they could try it.  I began to get phone calls with the words, "Damn! Don't get this stuff anywhere you don't want it, because it sticks so good you can't get it off!".  So when I found out that Pettit made a water-based paint, one I could used without fear of getting a tumor or turning into a deranged blithering idiot from exposure, I was immediately on board. Today we put on the first coat and I became an instant believer.

The instructions are detailed and clearly written and stress the fact that all bottom paint performance is dependent on the substrate prep, so pay attention to yours if you choose to use it. That being said, it's one of the few paints that can go directly over VC-17, which some previous owner had chosen to put between two layers of other paint of questionable compatibility, a fact that I'm fairly sure contributed to the large amount of paint blisters we had. Hydrocoat can be applied by sprayer, roller or brush and we chose the roller method, not having the facilities to spray and not having the time to brush. The paint rolled on smoothly and dried quickly on our warm day (84° and 68% humidity), but not the irritatingly fast dry of VC-17 which means that two people can share a tray and work at the same time without having to do the antics of VC-17 application to prevent it drying
before you get it on the bottom in the typical Midwest summer heat. There is very little odor, and what there is has a pleasant, clean smell. Need to scratch your nose? No problem. Just rinse your hands under the hose and the paint washes off.  Our blue tape line on the waterline pulled clean and sharp, although we didn't leave it on very long per some forum suggestion I had picked up along the way of researching the product.

We only have the first coat on and we'll update you once we get the black final coat on, but everything I see so far has me smiling big.

Yes, we were working around Tim's fiberglass repair which was still curing

Looks awesome. I have a friend who swears by hydrocoat. I had to use the other tumor generating stuff as the boat came covered in it, and taking it down was not something I wanted to do again. I don't think it's turned me into a deranged blithering idiot yet, but Deb says there are signs. "Just read your blog".
