3M™ 08883 Rubberized Undercoating (19.7 oz / 560 g) – Black Aerosol

3M™ Rubberized Undercoating 08883 is a premium rubberized undercoating that delivers corrosion protection and abrasion resistance while also providing sound deadening to help reduce road noise. It sprays on as a textured black finish designed to resist chipping, abrasion, exterior rusting, and weathering.

Key Benefits

• Anti-corrosive coating helps protect the undercarriage from rust and abrasion.
• Sound deadening properties help reduce road noise for a quieter ride.
• Textured black finish with a medium to coarse texture.
• Designed for one-coat build-up with no dripping, running, or sagging (as described).
• Aerosol spray format for convenient application without additional equipment.

Recommended Applications

• Automotive undercarriages
• Wheel wells
• Inside body panels (e.g., quarter panels)
• Door skins
• Trunks and floor pans
• Also described for areas like interior side of fenders, underside of hood, and trunk lid

Directions for Use

1. Remove all rust scale, oil, and grease. Surface must be clean and dry.
2. May be applied to bare or primed metal.
3. If applying to composite plastic (SMC/FRP) as a sound deadening material, sand the composite surface with a medium grade abrasive prior to applying (to increase adhesion).
4. Shake can for at least 60 seconds after the agitator ball moves freely.
5. Hold the can 10–12 inches from the surface and apply a uniform coat. Allow to dry 3–5 minutes, then apply a second coat. For hard-to-reach or small areas, use the snorkel tube with spray head (as described).
6. After use, clear the valve by inverting can and spray until free of material.
7. Note: Car trunks and interior areas require special attention to remove vapors (as described).
