I got a request to cut a simple lettered sign for a friend and they wanted me to use masking to make it easier for them to paint. I dusted off the roll of Oramask and now that the sign is cut I remember why I disliked the stuff. On tight corners the adhesive starts to let loose plus on some of the letters there are shreds of the masking material hanging off the edge instead of being a nice clean cut. I was using a ball nose but it is relatively new and still pretty sharp on the edges.
I have plenty of blue tape around because that is one of my favorite hold down strategies, but when I have used it on the back of a piece with a lot of detail cutting, the blue shreds make a real mess.
What are people using successfully? To my mind it has to have good strong adhesive and be not too soft so it cuts cleanly. Oramask is not it.
