Scuff the paint with a red Scotchbrite pad before spraying the clearcoat. It won't adhere properly if you don't and it will peel later. Use Duplicolor acrylic enamel clearcoat. Don't use the Duplicolor clearcoat from the auto touchup line because it's lacquer and will lift your paint. I painted my Raleigh Competition with acrylic enamel and it's holding up well so far. It takes months to fully cure enamel.
