Whether you're applying some cavity wax inside your doors, or spraying some Fluid Film up in your rear wheelhouse areas, there's a good chance you're going to need some new hole plugs. Some pickups, mostly GM, come with hole plugs in the rear wheelhouses to provide access to those hard-to-reach areas. These hole plugs take a lot of abuse from road grime and salt and will eventually crack when you take them out. We carry a wide range of hole plug sizes to help you replace your cracked plugs. If you've decided to spray cavity wax in your doors, you're going to want to plug the holes that you had to drill to access those areas. We carry hole plugs ranging in size from 1/4" to 1".
