So I filed out the Bondo from the compass and replaced with epoxy lumber. Very strong and still feathered nicely.
I masked everything out, and very tight to the letters and key lines ... then gave it a go with the airbrush. Upper area was repaired and given a the same color. It's behind the backboard and barely visible. And it gave me an opportunity to test the paint application. It'll tie together just fine.
Anyhow, first attempt at airbrushing wasn't going well ... little airbrush compressor wasn't up to the job and the Benjamin Moore paint needed serious thinning. Switched to my bigger compressor, 45psi and thinned the paint down - much much better.
A couple observations and lessons learned:
-Definitely need a respirator (I was wearing one). There was quite a haze in the shop when I was done blowing all that out.
-Not covering the upper pf with paper left me with the lightest of overspray ... naptha to the rescue, but won't do that again.
-Watch the airbrush tip for build-up. I had a clump that blew off, fortunately not while I was in the working area. You can see the splatter to the right of the SINK SHIP section.
-Don't put your wife's plant watering can that you're using to clean your airbrush near your feet. Knocked it over, cursed a bit, cleaned it up, then moved on.
Such a rookie. Moving on...
