I've installed a fair amount of vinyl including window perf...I haven't been masking the laminated window perf but I have been masking a lot more print and laminated graphics lately...I had seen a couple people advocating the mask in a lot of situations other than when vinyl is contour cut...
Anybody find an appreciable difference applying window perf if it is masked?
