For 1990-2009 cars

### Repair Procedure

Important: Follow these guidelines when performing SMC repairs:

• | Clean scuff and solvent wipe all areas to be repaired.

• | For added strength and durability, V-groove and reinforce on at least one side of an SMC joint using a tacky mesh tape or equivalent.

• | When partial panel replacement is performed, use two inch backing plates made from SMC or E-coated steel, as a reinforcement for all butt joints.

1. Scuff area where repair is to be performed.
2. Clean bond area with lint-free rag using a water-based cleaner.
3. Cracks should be grooved and reinforced on at least one side of an SMC joint 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 Goodwrench Structural Bonding Epoxy (part number 12345726), or equivalent, to the entire join' area extending across the cut lines and across the backer.

• | Use tacky mesh tape or an equivalent reinforcement matting.

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

6. Prepare the repair areas as necessary to resemble OEM appearance.

### Bonding Procedure

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

1. Prime all bare metal areas with an anti-corrosion primer such as DP90, or equivalent.

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

• | Always refer to paint manufacturer's recommendations.

• | Do not combine paint systems.

2. Clean 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 adhesive.

• | Use compressed air.

• | Do not wipe surface with hand or rag.

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