Sealers
WARNING: Always refer to Material Safety Data Sheet (MSDS) when handling chemicals and wear
protective equipment as directed. Examples may include but are not limited to respirators and chemically
resistant gloves. Failure to follow these instructions may result in serious personal injury.
The correct sealing of joints is essential to repairing the vehicle correctly. Sealers are used to prevent wind noise,
water leaks, exhaust fumes and dust from entering the vehicle. They also provide anti-corrosion barriers. Sealers are
applied to areas such as door and rear compartment hem flanges, wheelhouse, quarter outer, floor, cowl, roof and
other panel-to-panel attaching points. The following joint sealers are recommended for use depending upon the
application:
• Brushable Seam Sealer — A sealer intended to restore the original brushed seam appearance. It is used to
seal lap joints in sheet metal that are spot welded (for example, floorpans and cowls). Use a product
obtained locally.
• Roof Ditch Sealer — A self-leveling sealer used for drip rails, roof seams, quarter panels to rear deck and for
water leaks.
• Seam Sealer — Heavy-bodied, non-sag adhesive/sealer for use on standing cosmetic seams, truck bed
seams, tooled door skin seams and floor pans. Also used for water leaks and noise concerns.
Sealers should remain flexible after curing and must be paintable. Follow the manufacturer's directions for correct
application of these materials.
Any damage to originally sealed joints should be repaired by resealing. Along with attaching points of new panels,
open joints that require bridging of sealer to close a gap should be sealed using a heavy-bodied sealer.
