I measured the outside width of the cooler and the height to which the top 3 - 4 rows of the cooler would still be exposed, then cut the sign accordingly. I spray painted it per the directions on the can (about 3 layers) and secured it to the cooler with the double stick tape. Being that the tape is grey in cooler and would show from the front of the car, I further taped it up with some black electrical tape I happened to have handy. The result? faster warm up times (about 6-7 miles / 5 minutes) in 40ish degree weather up to 180°F. I don't drive her the short distance to work if temps are below 40°F. Here's a pic of what the DIY blocking plate looks like - it's on the Driver's side and it is hard to see... (exactly what I wanted):Attachment 75961
