On plastic molded decks, I use the following technique.
1. Spray the deck with flat back, (either floquil or testors), Let dry for 24 hours.
2. spray over the black with Testors armor sand, let dry 24 hours.
3. When dry lightly scrape the top of the deck with your #11 or a light rub with fine steel wool. in the tight areas you will need your # 11 blade.
This will bring out the moulded deck grain pettern. Email me direct at
jbgriby@cox.net and I send you back a few pics. of my decks.
