I'm going to paint lower sills
 

I bought the 1 base and 1 clear coat paint cans from paintscratch.com
and I bought 1 'bulldog adhesion promoter.

I'm going to paint it this weekend.

First I will wash and prep the lower sills with water, alchole and 600 sandpaper. Then I will put a coat of adhesion promoter and each 3 coats of base and clear coat paints.

Any tips for painting lowersills myself?
