So the overall report is positive. I can brush primer on for the first coat, so long as I thin it a bit. The Klass Kote sands great, fills well, and does everything I hoped for. Of course, the final primer will be sprayed, examined for bumps, puttied, block sanded, maybe another spray coat.

This is actually easier than what I used to do with resin and cloth. Because the Minwax is harder, I was forced to use the primer earlier. Works great!

Oh, and just because I was snapping photos, I also do plastic. Here's Leaky Boat Louie in progress.........
