Important: Follow these guidelines when performing SMC repairs:

1. Scuff the area where repair is to be performed.
2. Clean the bond area with a lint-free rag using a water-based cleaner.
3. Cracks in SMC should be grooved and reinforced on at least 1 side using a tacky mesh tape or equivalent
4. Sectioning joints require backing strips 50 mm (2 in) wide, which can be cut from leftover pieces of SMC.
5. Apply a thin coat of Structural Bonding Epoxy to the entire joint area extending across the cut lines and across the backing strip.

•	Use tacky mesh tape or an equivalent reinforcement matting.

•	Allow to cure according to the adhesive manufacturer's recommendations.

6. Shape and refinish the repair areas as necessary to resemble the original appearance.

Important: Use the following procedure when bonding undamaged SMC to epoxy-coated steel.

1. Prime all the bare metal areas with an anti-corrosion material.

•	Some paint manufacturers recommend a pre-primer when bonding to epoxy.

•	Always refer to the paint manufacturer's recommendations.

•	Do not combine paint systems.

2. Clean the bond area with a lint-free rag using a water-based cleaner.
3. Scuff both surfaces to be bonded using a scuff pad such as 3M's Scotch-Brite Red scuff pad part number 07447 or equivalent.
4. Ensure that the surface is clean and dry before applying the adhesive.

•	Use compressed air.

•	Do not wipe the surface with a hand or a rag.

5. Determine whether the adhesive is applied to the vehicle or the replacement panel.
6. Apply a consistent adhesive bond to the prepared surfaces.
7. Mechanically retain the panel in place in order to wet out the adhesive along the entire bonding surface.
8. Allow the area to cure according to the adhesive manufacturer's recommendations.
