I have been making worms for a long time(over 25 years) and have used most brands out there.
I like Dead on Plastix - it stays clear and does no yellow like some of the others.
But something is wrong, a nail weight should not pop out of the side of a worm after one day.
I mixed it well and heated over 350, even if I din't I don't think it should be this temperamental?
