This was after applying two coats of a urethane primer/surfacer - PPG Omni MP282. I wasn't very pleased with the application of the Omni 282 - it sprayed very dry and dried so fast that a lot of dry overspray was created. I had to work fast to keep a wet edge when spraying. Part of that, I'm sure, was due to using the fast reducer and hardener I had purchased in anticipation of spraying in cold weather. Well, it turned out to be an unseasonably hot day when I sprayed it.
I block sanded this with 320 then finished it with 600 by hand. I wanted to get a slick finish so that I can preview the flatness to see if it's ready for paint.
It was rolled out of the shop to be washed down. All the accumulated sanding dust was rinsed thoroughly, inside and out.
While it was wet, I had the opportunity to evaluate the flatness by examining the reflections on the wet surface. Found just a couple spots that will need further attention.
