Holy crap!!!!!! make sure you read everything , every review , watch every you tube vid, a buddy and I bought a bunch of film and activator........most madding thing I have ever tried. There are so many variables you may get it right the first time or not. film thickness, quality, manufacture , humidity, ambient temperature , water temp, size and shape of your piece, type of activator ,quantity if said activator, spray pattern , droplet size/ how fine is the mist, again quantity, surface prep, did the chem you do prep with compatible with the activator, once you get it in the water getting it out. again with the amount of activator and how you lay it on the film, did I mention the activator....or the water temp. how about the perfect tome to let the activator activate. again the the quantity......AAHHHHHGGGGG..... I got so fed up I took all my stuff to a guy who did has a small side business, turns out I may have gotten a bad batch of film, or it was the wrong kind of activator, of it was the film , he couldn't get it work correctly either. so in the end I have like 10 rolls of awesome looking film, all of it may have been ruined because I opened it up to look at it while I was in my garage and it was exposed to the humidity , who knows. good luck and god speed, keep the firearms unloaded and in the house , just incase you get that fed up. haha
