I cracked open my first can of Interlux "Brightsides" paint. It is the opposite of the primer... runny. I think you could spray it without a thinner. I am using a close nap 1/4" pile microfiber roller to apply this paint. the small roller makes to many tracks. this covers the plank in one pass. The paint also goes a long ways. I took about 1 hour to prep the boat. And about 2 hours to paint.
It'll do I guess.... :)Time: 3 hours
