It is good if you want a hard edge to whatever it is you are masking, tis pricey though. Yeah sure, $30 for 25ft roll about 4" wide. Go to the grocery store, and get the glad cling wrap, basically the same thing, 25ft roll, 12" wide for probably under $7. Maybe doesn't stretch as far, but you have a wider roll for less than 1/3 the money.

The poster putty as well...the white seems to work better than the blue....something in the blue stuff that can leave marks/stains on your paint. Does work well for doing soft edge camo, so long as you spray over it at the right angle.
