While I use it very rarely, I've got some Humbrol masking agent and I haven't really been very happy with it. It seems to be very gunky and go on unevenly; when I try to get it off it breaks into teeny little bits that are a HUGE pain to remove. As such I've lately looked at several other products, including Microscale's "Micro Mask" and some stuff at the local art supply store from Windsor & Newton and others.
What's the best masking agent out there and how can I make the most of the Humbrol stuff I presently have?
Thanks guys!
