So what are you guys using for block out tape? I have tried R tape is ok but still to sticky some of the time and not a lot on the roll. also have used painters tape but thats kinda pricey and rips too easy if I could find a tape that releases as clean as painters tape but is more tough in the corners not ripping so easy I currently use shipping tape from the dollar store believe it or not LOL it works very good sticks very good but some times I guess depending on the batch it leaves glue nothing too serious but I want something cleaner and easy. anyway suggest away prices and and where to get if you can thanks!
