Hey guys

I have about 500' of 3/0, and 500' of 350 MCM i need to mark red, white and blue. Thats a LOT of tape. I have not installed the wires yet so I attempted to use spray paint. We tested out a can of Krylon Flat white, and it looked okay, but did not work so well. Took about two cans to do 80 feet. Can I get any special type of spray paint designed to work with electrical wires?
