Instead of buying prepainted spinnerbait heads so i can build my own spinnerbaits, I was thinking obout buying lead heads, so each can be a seperate color instead of buying 5 packs. What kind of paint should I use? Since I dont have an airbrush, Will spray paint work, and if so what kind? Also what should I use for an epoxy coating.

Regular old Krylon spray paint works fine on lead.  Whatever you use (assuming you don't use powder) you'll have to seal it with epoxy otherwise it will peel off very fast.  Just use Devcon which you can find at walmart for like $2.69.  Make sure your mix is precise on the epoxy.

good luck.

Which kind of Devcon? I've heard that the 2ton is the best but is this true?

The 2 ton seems to work best for me.  For painting lead, I'd use the stuff that cures quickly.  If you hang your jigs, the longer-cure time stuff can slide down the head.
