20 oz Opaque Black Rubberized Undercoating

This 20 oz aerosol delivers a rubberised compound that forms a tough, flexible shield against moisture, salt and road debris. It dries quickly and remains exceptionally resistant to abrasion. The opaque black finish suits underbody, fender, panel, frame, hood, door and weld-joint applications.

VOC compliant formula and quick-dry performance

The coating meets VOC regulations and will not crack or peel once cured. It deadens outside road noise while sealing trunk interiors and firewalls on motor vehicles. Quick drying reduces downtime between coats and speeds up the overall job.

California Proposition 65 warning

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Check local regulations before ordering, as some states may restrict sale. Ensure the surface is clean and dry for proper adhesion.

Questions about this item

How often does the rubberized undercoating need to be reapplied on a vehicle underbody?

The coating forms a tough, flexible shield that will not crack or peel, so reapplication is only needed if the surface is damaged or worn through.

What is the first limitation you hit when spraying large areas continuously?

Each can holds 20 oz of product, so coverage stops when the can empties and a new one is required.

Does the spray produce strong fumes or heat during extended use in a garage?

The formula is VOC compliant and dries quickly without generating heat; normal ventilation handles the fumes.
