Hull blasted, now what?

The plan as of today is to patch any cracks or holes with high-strength Epoxy paste filler.

Spray two layers of barrier coat with Petitt Protect and two coats of VC-17.

A roller works great for applying bottom paint. (and a brush for touch up and the boot top) and since it's the bottom, you don't really have to worry about imperfections. As long as it's covered, it's good

I did my first and second bottom jobs with rollers and the paint lasted 3 years on the first one and it will be 4 years on this second one.

I did roll and tip on the topside hull though which will need to be completed again this next time.

The topside paint was $85.00/gallon. Bottom paint was that expensive CSC Micron Ablative which goes for around $235.00/gallon but there are cheaper paints out there. My bottom usually takes one gallon plus one quart of that paint to complete

Also, the guys working at the boatyards here always use a roller when doing bottom jobs.

The barrier and bottom can be rolled as a DIY job, except for high end racing programs. I have been beaten in one design races by a boat I rolled the bottom on.

Do you plan to haul the boat each winter?? If so, ablative paint probably makes more sense. Some hard paints don't recommend storing out of water.

Several of the captains in my club use VC-17 and they roll it on. That's what I'll do once the barrier coat is on.

I'm spraying the barrier coat because I have the equipment and it produces a better result. One of the captains had problems with the barrier coat when he rolled it on and had to sand out some areas.

We're in the midwest so we haul out every winter.

Interprotect. And VC-17 is a good Great Lakes paint.

Fair in the through hulls before you do anything. It’s a small thing but in boats like ours every little bit helps!

What compound do you use to fair your through hulls?

I finished the bottom painting this week. It was really a big job on such a big boat and took the entire day.

Here's what it looked like before I started:



Here's what it looks like now:
