| all right guys here is the scenario.
I am building large wooden "walk the dog" type baits but am having a problem with durability of finish. I'll give the rundown to figure out what the problem is.
When the baits are fully sanded, I epoxy all the screw eyes in place and then coat the bait with a lightly thinned ( denatured) coat of epoxy to seal it. after a full 24hours or more, i wet sand the epoxy with 220. i then clean the bait with water and allow to dry overnight. i then prime the bait heavily and allow it to cure overnight again. The paint process is fairly simple, only 2 colors and i space the coats out only enough for the paint to flash. i am rattle canning with boyds enamels. After the paint has fully cured, I coat it with 1 coat of thinned epoxy, let it cure overnight, then another, cure, another, cure, then hang the hooks. thats three finish coats of slow cure epoxy, about 3/32" build
now the problem is that the epoxy is almost "flaking" off where the hooks rub, but it only goes as deep as the " wood sealing" coat of epoxy. it doesn't go to the wood. this isn't right. only after 4 or 5 hours of chuckin, the paint is thrashed. the baits don't get waterlogged at all, but they get ugly quick. durabilitly is a primary concern for me with these baits.
help would be GREATLY appreciated. i have a couple of ideas, but don't want to lead the topic, so what do you guys think?
thanks

Location: Freedom, WI | I would suggest not to thin the top coats of epoxy. Since it it is not soaking in like the base coat it needs to bond together. Try 2 thick coats instead of 3 thin ones. |

| I think you nailed it Roger.
If you thin the top coat, or don't wet sand between the layers, it doesn't have anything to "cling" to. Thinning takes away, or weakens that property if it has nothing to penetrate into.
Envirotex makes several top coats, and when I re-do top waters for people who are worried about adding too much weight, I put on 2 coats of Envirotex, and wet sand between coats and haven't had problems with flaking. If you aren't worried about the weight of the top coat effecting the lure, try putting on one coat and turning it while it cures. You can build up a very nice, thick top coat that way.......as long as it doesn't sink the lure. |
