i have to agree with staying away from krylon. duplicolor is good. strip, scuff, clean, prime, prime, sand, clean, prime, prime, paint, paint, paint, paint, clearcoat, clearcoat clearcoat(until you use the whole can)

actually...krylon makes this stuff called crystal clear glazing. it's a thicker clearcoat. it's also pretty duable. i suggest it.
the key to all of this is time. take lots of time.
