i have never dyed or dipped,dont have anything to do it with. i painted my traps last year, but if i am going to spend some money on more, i wanted to be proactive in longivity of the trap, so i was looking at differant dips, dyes, waxes etc.., asked about the cold dip because that is something i can do at this stage, but i dont want something thats is going to hang up the preformance of the trap, my traps i now have been preforming with a coat of rustolium brown on them, maybe thats what i'll do this year ?
