I'm going to install a set of Husky molded splash guards on my 2011 Silverado. The question I have is on the rear fender which has (what appears to be) a small piece of clear tape on the corner near the tires. To install the splash guards, I'm going to install the 3m clear film which came with the set. So...do I remove the tape/film that came on the rear fender or leave it before I install the 3m clear film? Any help would be appreicated!
