What is the purpose of seam sealer?

Explanation:
Seam sealer is placed on joints where body panels meet to create a watertight seal. Its main job is to keep moisture out of welded seams and panel joints, which helps prevent rust and water leaks inside the vehicle. The material stays flexible so it can move with the panels as the car expands and contracts with temperature changes, reducing the chance of cracks forming. After cleaning and preparing the seams, you apply seam sealer along the joints, let it cure, and then proceed with primer and paint. It isn’t used to prime surfaces, apply the topcoat, or fill scratches—those tasks are handled by primer, paint, and body filler respectively.
