Chapstick's Profile

I suppose this has been answered by now. But any finished coat can go over any primer, you just cannot put a latex finish coat directly onto a (likely glossy) oil finish coat. Oil primer (although sometimes smelly, I would suggest using Zinsser Odorless to avoid that a bit) will work great on nearly any surface because of its strong bonding quality (and a few other reasons...)
Also, the makeover looks great!
