Ultracoat is a more workable covering, but I have found that certain colors tend to be different to apply for some reason. Monocoat is a good thick covering and it will stretch thin and tight. Ultracoat I can do compounds and curves a lot easier but i have had trouble with it where it joins to itself stretching and leaving glue lines, it comes off with thinner. I think they both are a good quality and I choose each by the job I am going to do.
