So when I bought my car, I made a huge mistake and allowed the dealer to drill my license plate into my bumper. Now, I bought a plate relocator and I'm stuck with drill holes being exposed. What can I use to remove these? I'm avoiding trying to buy/paint a whole new bumper at the moment; I thought I found a bumper filler in which I can sand it but I don't know what to buy and what to do. Thanks for the help!
