Thanks guys, I'm pretty sure I'm going to leave them un-coated. But I have noticed it's been 2 years since my '66 Superhawk resto, and the fins are starting to corrode a bit, and they're tough to get completely mint again (I bead blasted them). I think the old Superhawks had a coating on them too, but no one seemed to be re-doing them either. So, just trying to get a concensus here.. Seems like I'm going to paint the head and cylinder though, most seem to agree that they were painted. There quite a split on what to use there though, some guys liking the VHT and others, the Duplicolor. I'll figure that out later..Thanks, John.
