mark and I have talked about this wrinkling issue and since I started using testors white and pearls I have not had one issue with it- just my .02- my procedure is as follows if it helps- paint bait as usual ,drying with hairdryer between coats- into hotbox @110 degrees for 15 min. or so- remove and dip first coat of ac 1315- back in hotbox for 15 0r 20 min- dip again- usually do this 4 times and bait is done the next day- a lot of times I will leave baits in the box for an extra 12 hrs or so while I am at work and they are rock hard when I return to them-no smell at all- I have done probably 60-70 baits with this process in the last month or so and not one problem- got on a good school of smaller bass and caught probably 50-60 on one little john I had painted. it was pretty scratched up as you can imagine- took it home, removed the hooks ,hit it with some 500 grit sandpaper, and two dips later I could have sold it as a new bait- as far as toothy critters go ,an epoxy is probably the best bet- as far as bass fishing cranks go, i'll be using this stuff- thanks to mark Paulson for the insight !
