3M 7000148242 Self-leveling Seam Sealer 200 Ml

Product Description

The 3M 7000148242 is a two-part epoxy self-leveling seam sealer packaged in a 200 mL cartridge. It is formulated for structural seam applications on vehicle body panels, including roof ditches, door skin hem flanges, rear body panels, tail light areas, and wheel well flanges. Applied directly over primed metal, it flows into seams without manual tooling, cures with no shrinkage or cracking, and matches OEM-style seam profiles. Work time is approximately 15 minutes, and the cured material is ready to paint in approximately 30 minutes. Automotive body technicians and collision repair professionals install this product as part of panel replacement and seam restoration work.

This seam sealer is suited for collision repair and auto body refinishing applications where OEM seam appearance and structural integrity must be maintained. Typical use cases include door skin replacements, rear quarter panel repairs, and wheel arch seam restoration on passenger vehicles. The self-leveling formula eliminates the need for additional smoothing or tooling after application, reducing labor time on production repairs.
