Select and prep test piece.
Fill bucket partially with water. ( for us in fl room temp seems fine)
Add a half tablespoonish of ajax. Swirl and allow to sit for a few mins.
Dawn, mask.
Spray paint and clear coat into cups.
Now speed is critical.
From close to waters surface begin adding paint or clear coat. Allow it to spread for a bit before adding another color, Then swirl it up and quickly dunk with a back and forth motion as you submerge.
So far have only attempted the test pieces pictured. Far from having it down, yet:).
