Assuming you washed it well and sanded any spots. Tape the edge with the blue tape so the edge comes out nice and straight as well as sharp. Use a commercial
paint shaker at any paint store so it is mixed as much as possible. Mix it as you work with it. Use a roller for as much as possible and a throw away brush to get in the detail areas. Don't paint over stuff that isn't supposed to be painted like depth
transducer bonding plate, zincs. Move along and keep a wet edge. Change the shaft zinc if it even as a little bit of wear. It's just too easy and cheap
not to do it now.
Get someone at the yard to help with the jack stands so you can get under the pads. This isn't something you want to screw up with.
If you need to do a second coat later you can't reuse the roller or brush.
It's amazing how large your boat is when it's hauled out.
