I'll have to look at the can and let you know lol I took fine sandpaper and just did a light overall run down on the entire wheel. Wasn't perfect but i don't think it has to be. The 1 coat of white primer i let sit for about 30 minutes until it was mostly dry then put the first coat of satin black on. The first coat let sit for about 45 minutes second coat about an hour then did 2 quick back to back (about 10 minutes apart) coats of Gloss enamel. Looks good so far they were mostly dry when i put them back on but it was getting cooler so then weren't going to dry any faster. The 2 wheels took me about 4.5 hours total but i also did the center caps and the inserts on the wing.
