I ben usin a sharpened piece of 3/32 weld wire to melt the hole-on the back down towards the ass of the lure-usually a cc redfin. then I put it in a sink full of water and rap it against the side to let air out and water in, when the lure sits with the nose pointing up @ 45 degrees I say outloud, "you're loaded", and seal it back up with a hot butter knife-don't tell the old lady-then put a drop of zappagap to smooth the profile
done me rite sofar
