If you priced out the hooks and the paint needed for these, would they be worth the money compared to buying them from Rapala? Would good ole gorilla glue work for the eyes and fins?
If you're looking @ these you probably already paint something and anyone that doesn't have at least a dozen extra hooks laying around in a few sizes is not well prepared.
To your question Slide: I have used Gorilla Glue and know that it is moisture activated/cured. Always wondered about the water resistance/proof qualities considering that and, in fairness, have not tested it. So, no help on that from me.
My preference for gluing the tail would be regular (not fast setting) epoxy. Fast set is fine for a number of things but the regular (60 min cure) is the most waterproof iteration of epoxies. The eyes should already be self adhesive with waterproof stuff. When applying anything self adhesive I usually apply a light coat of Pliobond on the surface of the target (not on the tape, eye, whatever) and let it pretty much dry. It doesn't take long if you keep it light and Pliobond sticks better to anything that the self adhesive stuff by itself. Don't rush it and apply the "sticker" while any of the Pliobond is still wet. The solvent will liquefy whatever adhesive is on the sticker and perhaps even melt part of the sticker itself. When it is dry to the touch but still somewhat soft is the right time.
Here's a quick, crazy option to painting:
Pro Skinz - Jig Skinz Yep, it's another coupla bucks but no way can I paint like that.
I wish they made one size smaller, 3/16 (jig body looks to be 1.25") is still large for all but the most giant perch. Maybe I'll bite on a few anyway, I like to play.
If you buy the "kit" and the Skinz you're $3.20 into a jigging lure plus your time. If you paint it gets really cheap. I don't think I ever bought a JR for under $4 and more like $5 - 6.
