Well, I ran into a problem with this stuff. It will not adhere to sharp contours in the body, as it dries it will stretch over contours and you get air pockets under the mask. My test body was a proline bulldog truck, that has some sharp contours in the cab area. The first time I got air pockets I thought it might be because I didn’t allow enough dry time between coats, so I started over letting it completely dry between coats. The air pockets were not as bad but I still had them. I did test cut a window and it cuts very nice and peels very easy, so if you are going to do a body with no sharp contours or just flat panels it should work good.
I am trying one more test mixing it with fastmask to see what happens.
