About to paint car, Need suggestions Options

[wuhukf]

Hey, I'm going to get my car painted in a week or two and I've chosen Gunmetal Pearl for the color. Since I'm going to be getting the 404 front lip and side skirts molded onto the car before it gets painted, what performance/maintenance things should I do before? Since I won't be able to easily take off the bumper after this is done, I'm trying to do everything that requires the bumper off now. I've already ordered the aluminum Koyo radiator, already have fog lights, and my cold air intake can be reached by taking off part of the splash guard. Please give me any suggestions, thanks a lot.
