GM Service Manual Online
For 1990-2009 cars only

Important: Do not apply an excessive amount of sealer to an area. An excessive amount of sealer will take longer to dry and could come in contact with body parts or components within the immediate area of the body repair.

After welding any body parts, the areas must be wire brushed and cleaned. When this is done, prime the area with DP90LF Epoxy Primer, mixed with DP401LF Catalyst (or equivalent) before applying the recommended sealer. This will not only waterproof the weld seam, but prevent exhaust gases from entering the passenger compartment.

For proper sealing locations, refer to the following illustrations:
