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.
