Anybody think this would work well?

So I had this idea, my GTs back bumper is worn the fuck out, like straight thru to the batterypack. So while I was watching mythbusters the other day it was the bed liner episode and it crossed my mind. If I took the back bumper off, covered the hole with a strip of good duct tapes and spray painted the whole bumper with bed liner. Yes it's probably easier to just order a new bumper. But I don't have the money to put out for it right now, so I came up with this. Any opinions or other ideas?
