It’s a 55-56 Chevy Station Wagon bumper that the owner was about to spend over $500 to Re-Chrome. It was restored to a MIRROR finish with a nickels worth of StrongArm Penetrating Oil Spray! The bumper is cleaned one side at a time, and water is dumped on it to show how waterproof it is and the water runs off like on a ducks back. This bumper will be corrosion proofed for years on end in storage after this StrongArm Sprays simple one minute treatment. The bearing of the brush turns the corrosion into the fine grit rubbing compound with StrongArm Sprays penetrating into the surface instantly.
