Just try to not get too much into the hook hangers/pull to begin with and if you do you can heat it a bit with a hairdryer and blow it out with a simple puff most of the time. If you have excessive amounts after it dries just drill it out, just be careful on the line pull as any abrasion will of course compromise you line.
If you want to continue using D2T, try taking a stamping/crafts heat gun or blow dryer and heat the bait first before applying versus heating it afterwards to help level it. Just work quickly and efficiently and make sure everything you want and need is laid out before you mix up epoxy. Heat it, coat it and try to not overbrush the epoxy, and brush one direction primarily helps eliminate extra tiny air bubbles put it on the turner, do the next couple and then come back and just lightly hit them with a little heat if needed.
You can also go to Lowes/Home Depot or ??? get some acetone if you don't have it already and after mixing the D2T add enough drops of acetone to thin it by about 1/3 and mix the acetone in thoroughly. This will help it lay on thinner and will extend the working time for you. Or you can just switch to ETEX a much slower curing epoxy and be prepared to let in spin a long time and you will have to apply a 2nd / 3rd coat.
ps: l like Manns -1 baits, just repaint them and keep em!! Great for grass and thin/early lilly pads. I did a couple repaints as some of my early work as well and I definitely still throw them.
