on closer inspection of my previous batch of lures, a couple of them were quite poorly coated as well. so that might rule out the Vallejo gloss, as I hadn't used it before. so it may be back to thinking that I didn't mix the etex thoroughly enough. but it looks more like the etex reacted with the lure, like say the lure was handled too much and contaminated with oily hands. even though I was very careful, doubly-so with the last group. something clearly touched them I would say. more attention to cleaned lures prior to coating in future sessions.
yes, the Vallejo gloss was definitely cured, a couple days sitting I think. I wasn't sure about the etex with foil, so I used a spray instead. I will try the etex next time, over the foil.
I used to just do one coat of etex, but a fairly generous one. that always seemed to work well. but then I was having the occasional lure that would have a messed up action. I learned that my thick layer of etex was changing it. my lures have a cup-face for their action. so I then switched to two thinner coats on the lures, and leaving the cup-face with only one thin coat, so the action wouldn't be affected.
