Important Note for Professionals

3M recommends this sealant exclusively for external or non-passenger compartment sealing applications on automobiles. It is not recommended for interior passenger or trunk compartment applications due to a reported objectionable residual solvent odor that can persist for up to a month. For interior applications, professionals should consider 3M Urethane Seam Sealers or 3M MSP Seam Sealers.
