Directions for Use

NOTE: 3M Best Practice is that all sealers, unless designated specifically for use on

bare metal, be applied to properly prepared automotive paint or primer. Applying over

bare metal may not provide adequate corrosion protection.

Acid etch primer is not recommended to be used in direct contact with any

3M seam sealer. Residual acid can weaken the bond.

1. If applying to bare metal: Abrade the surface to remove all surface contaminates

exposing clean bare metal.

If applying to primer or paint: Scuff the surface with a fine grade abrasive or scuff

pad.

2. Wash the surface with an appropriate VOC compliant product for removal of surface

contaminants.

3. Open the quart can and brush/tool seam sealer onto desired surface. Be aware this is a

fast-drying sealer, be prepared to work quickly.

4. Tool or brush to desired appearance.

5. Wait to dry before applying paint over the sealer. Thicker applications of seam sealer

will take longer to cure before painting. Stated dry time is for 1/8 inch thickness.

Applications

A multipurpose, fast-drying seam sealer that is easily applied with a brush. Duplicates

OEM appearance in areas where a brushed seam sealer was originally used. A typical

application would be seams in the engine compartment since it is resistant to fuel and oil.

NOTE: This product is not desirable anywhere inside the passenger compartment of

the vehicle since it contains a solvent, which if not allowed to fully dry, can leave a

strong smell in the vehicle.

If a brushable sealer is needed in the passenger compartment or inside the trunk, a better

selection would be a one part, moisture cure, urethane product such as PN 08360, 08361,

08364 or a two part product such as PN 08308 or 08310.

Storage and

Handling

Store at room temperature. Rotate stock on a “first-in, first-out” basis. When stored at

the recommended conditions in original, unopened containers, this product has a shelf

life of 12 months. Always use in a well-ventilated area.
