Is there any where on this board that has detailed info on how to install a Billboard on a Cuda, especially the part where you need to cut it away from the rear marker lens, im confused bcuz of the pre mask, i have been told that the premask has to be left on until the vinyl is installed and dried for at least 3 hours...if this is so how does one overlap it, does one remove the pre mask in this overlap section and or leave the backing on until the rest is on and dried, then come back later and complete the over lap part, or do I relief cut a wedge out of the graphic itself removing both backing and pre mask for that section?
