The stuff I had problems with was a roll of pearl white. I have pearl wine (2 rolls that worked wellexcept if abused the color will smear which I take responsibility for and not concerned). I also have a roll of pearl copper which I haven't opened yet. I have used 2 of the neon colors also and have been happy with them. The neon colors are different and can be finicky but I accept this as they are not so basic of a product and understand that I may have to use extra care or extra prep time or whatever to get something out of the ordinary. Kind of like a "hottie" as an analogy where it looks good but you know its going to be more maintenence and work. You know this going in. Now, with my roll of pearl white, the texture of the film itself is like rough like an orange peel and has a powdery feel to it like coated with a dust of talc. The film that covers backside seems to come off differently. It doesn't stick as good, shrink as good, cut the same, feel the sameor look as good. Nothing about using this stuff is as good. I have used regular colors of monocote without a problem but do notice that some colors handle better than others. I have never tried transparent colors of any kind. I have used one roll of Ultracote. It was green apple. I worked well but didn't seem to go very far as the roll is narrow and I had to cut it lengthwise to cover the wings. I don' think I really care for the protective film on the back, but still undecided about this as I will see how storage and repair jobs go. I would like to know how to recognize a roll of Monocote that may be troublesome without having trouble! I have heard about smell, but I think it all smells. I dont use the word stink like they did cause so far I think it all smells good. The texture of the white pearl I talked about was the best indicator so far that I have witnessed or heard of. Don't know if this occurs in regular colors though, may be a "pearl thing". Pearl wine is not like that though, and I dont think the pearl copper is either. A hobby store 40 miles from here has alot of old dusty Monocote that I may try. They want alot of money though like 18.95 a roll and maybe more for neon. Guess thats why its dusty! But paying to ship back return stuff is expensive and a hassle also I just wish I knew how to predict a good Monocote experience, because when its good, I pesonally think it to be the best. I know if I ever see a regular color that feels like the pearl white I won't use it. I am also done with pearl white itself as I don't want to see this again. Would like to know more about this though, like if anyone has a roll of pearl white different than mine? Has anyone been able to predict a bad experience in some other way?
