I believe what was told to me about dipping, two dips equals about D2T. Spraying, dunno. I really got to make booth. I would really like to spray, it would make it easier.
As far as jointed baits there a few things you can do. Rubber band around the hinge, BobP (I think) told me about a liquid frisket film. I couldn't find that around here, sooo..... I started thinking what could I use? I came up with White Out, used to cover up writing on paper. A little clean up will be needed.
