Single stage VS B/C
Well said,OSB.
Remember the days of Laquer paints. 3 coats color wetsand (solid color),3 coats clear wetsand (manually)eventually down to 1200 grit back then and buff like hell!
(No wonder why I have RA in joints of my hands)
We used to spray Laquer in jambs/firewall and clearcoat with Enamel clear for durability.
Like RRR said, a monkey blindfolded can paint bc/cc. The prepwork is where the skill must
be there.
