Review title is I love Microscale products but this is not one of them [SEP] This masking product does brush on easily and does work on the areas you want to protect, but it dries very stiff and is difficult to trim without it wanting to lift off from the plastic. And it is difficult to tell if an area is successfully covered since it has just a slight blue tint to it. When dry, I can't tell sometimes if it is still on the area I want to protect. If this product wants to be perfect it needs to be more flexible, stick to plastics a little more, and have more pigment in it to show clearly where it has been applied.
