Just like when priming and painting your car there are a lot of choices when it comes to picking a seam sealer when refinishing or repairing your project. Seam sealer is made to cover and seal areas where panels may have been welded or overlapped. It will keep the seam from getting moisture in between panels and rusting out. As long as you use the correct seam sealer and prepared the panel correctly it will last the lifetime of the vehicle. We decided to cover the seam sealers that we offer and their best applications.
