I have a contract to wrap backup generators. They generate a lot of heat so all the doors have 1/4" deep louvers. So far we are stumped on how to get a clean look. We have tried heat but when you cut the vinyl to vent the louver it is all stretched out and will not lay down smoothly. Does anyone have experience with this? We are using Avery MPI 1005 with 1360 overlam.
