You guys will think I'm nuts...
This afternoon my next door neighbor applied a spray-on bed liner coating made by Dupli-Color.
I said hi and wandered over for a peek at his handi-work.
The second I saw the finish and texture of this bed liner coating I knew that was what I wanted on the glareshield of my 727.
It's flat, coverage is excellent (better than anything out of a can) and I can't describe the texture. It's smooth, but it's not. It's almost like a cast iron finish, but much smoother.
The stuff is a polymer (plastic) and dries to the touch in five minutes. The down side is that it's eight buck a can. You should be able to do the entire top and the underside back to the MIP if you budget it out right.
I'll post a picture in a bit. It's still outside on the 'bucks.
