I have used it...and it's "ok". It adds some color...and some scent. It's quick and durable. A quick and easy change kind of thing.
What I don't like it that it's not a "clean" color....it muddies the color underneath...big deal??? Depends on the person.
If I want red tipped claws on my Mud Bug ( I do!!!) I mold the tips in the claw mold ...then add them when I mold the bait.
If I want scent...I add it later.
But I'm kind of fussy on color...I want the claw tips to be RED...not kinda of red/brown. Or Chartreuse...not a muddy chartreuse/brown
