I found a product called "Art Mask". It's a lightly yellow tinted latex based frisket. It's little easier to see compared to rubber cement but it's still pretty hard to see unless applied very thickly. It also is very watery and hard to apply. One quality I did like is that it doesn't have the offensive and toxic fume that rubber cement has. It has some slight ammonia smell but not bad.
I got the job done well enough so I'm pretty happy. I'm becoming a known face at a local art supply store.... I'm there every weekend!
