its a good, detailed write-up for super high quality work.
when i shaded mine, i didnt have the patience that you did, so i never wetsanded, didnt wax either or buff. All i did was.
3 coats of shade (drying between)
2 coats of clear.
they turned out good IMO, but i suppose side by side with yours, I would see the difference made by your procedure.
