I may have found a culprit. I went out to the paint-desk last night and painted another lure. between colours, waiting for paint to dry, I looked at everything and broke down my previous painting session. I was sure everything was the same as usual, but you never know. then, yup, I spotted something.
recently, I have done some foil lures, and a couple using metal flake. my plan wasn't to use the etex on these anyway, assuming it wouldn't adhere well. but I had bought a Vallejo gloss varnish recently, planning to use it on the metal flake to seal it before hitting it with a spray clear that I sometimes use. after that last batch of lures were good and dry, for some reason, I then used that varnish on them as well. i'm guessing I decided to try it since the previous batch of lures had some issues. but I think that previous batch was maybe more due to glitter, I will have to closer inspect. but the last batch were glitter-free, removing that from the equation. then they really had a repelling issue, like never before. it HAD to be from that new gloss varnish.
so last night I coated a test board that I test paints on. I will now try etex over it and see what happens. pretty sure it will be the problem. the lures actually looked pretty good with just that gloss varnish on them. nothing like an etex layer, but not bad. but I doubt it's a strong clear that is designed to hold up to fishing rigors.
live and learn. that's what it's all about. trying new things is how we find what is best and what is not. I do really want to try the KBS, but it's not really available up here in canadaland, from what I have been able to find anyway. I tracked down a company in alberta who brings it in though, so I may try to see if they can ship over to bc.
but I will probably always use etex for some lures. when it works right it is so awesome. just frustrating when it's always performed well, then suddenly things just don't go right. and when one looks closely, they'll probably usually find it was a mistake on their part. in fact, just writing this, I now have realized I also used a stir-stick that was used previously. now that probably wouldn't/shouldn't have contaminated it, but, not a good idea. I have a package of new, clean ones and should have never used an old one.
