Standard Operating Procedure for the combination of seam sealers and spot welding (STRSW), or weld bonding. Work quickly to perform spot welds while the seam sealer is still uncured. Remember to reapply 3M™ NVH Dampening Material and Pillar Foam as needed to match OEM. Restore corrosion protection with 3M™ Rust FighterI™ or Cavity Wax.
