(1) Remove Flash

(7) Wait 2 days
(8) Apply Decals
(9) Wait 1 day
(10) Apply 2nd coat of Gloss Coat
(11) Wait 2 days, then rub/buff in Mequiers Wax
This will render a nice deep finish, especially true with metal flake type finishes, and decals will appear to be part of the finish itself.
*A 3rd coat of Gloss Coat before waxing is optional, just allow good dry time between coats.* The waxing creates the "Metal" look.
Many many styles, this one's mine.
