Depending on how thick you glom it on, you may be able to get by w/2 coats. Usually, it seems pretty rough still at that point and seems like it could capture a lot of grit/dirt in the crevices and voids. My impression is that three coats is about the minimum for bars that will stay pretty clean, be wipeable, follow on coats gloss them up more, and fill in more voids. However, the gloss wears off (for me anyhow) and it starts looking sorta worn/leathery.

I like about 6 coats, let dry 24 hours between coats. At this point, it looks like candy, shiny, etc, really too much, imo, but it wears in pretty quick and the gloss gets knocked off. I'll ride it 24 hours after my last coat.
