. Alluminuim spray paint
From the 5th – 9th coat, wet sand the
Swatch until its smooth.
Step4

Spray two coats of Matt Black Spray paint of the

Swatch and let it dry for 25-30 min.
Step5

Mix a ½ Golf Ball size of clear Silicone sealant, 3 peas size of

Ivory Black watercolor, a light spray of high Gloss Jet Black
Replicated Finish spray paint into a cup and mix for 2mins. Apply the mixed paste

on to the Swatch evenly with a Painters knife, let it dry for 24hrs.
