Blaster Surface Shield – Complete Auto Undercoating Corrosion Protection (12 oz Aerosol, Pack of 6)

Durable corrosion protection for your vehicle’s undercarriage

Blaster Surface Shield is a complete undercoating spray designed for automotive applications. Each 12 oz aerosol delivers a smooth, controllable mist that forms a protective film over exposed metal. It’s engineered to shield critical undercarriage components—from frame rails to suspension mounts—against moisture, road salt, and everyday wear. The result is a finish that feels durable to the touch and looks even in finish, without a harsh odor during application.

What makes it work

• Corrosion protection up to 2 years under typical driving conditions.
• Uniform spray pattern for precise coverage and a consistent film build, avoiding peaks or thin spots.
• Lanolin-based technology combined with a non-toxic, low VOC formulation for safer use.
• Low odor formula that keeps your workspace comfortable in small garages or bays.
• Safe on metal and compatible with surrounding plastics, rubber, glass, and wiring.

Real-world scenarios and benefits

Maintain the integrity of aging or new undercarriage components, or prep for winter driving where moisture and salt are common. The protective film remains flexible to tolerate road debris and temperature changes, allowing routine washing without compromising the coating.

• Pre-winter protection for frame members, rock rails, and brackets in areas with icy roads.
• After-wash maintenance to reinforce existing protection and refresh neglected surfaces.

Pack details and usage tips help you plan ahead. The product comes as a 12 oz aerosol per can and is sold in a pack of six, offering ample coverage for multiple projects or a full undercarriage treatment across a vehicle lineup.

How to apply: shake well, apply in dry conditions, hold the can at an even distance, and use a steady sweeping motion to achieve a uniform layer. The result is a smooth, non-sticky film that dries relatively quickly to a protective finish.

Safety and handling

• Non-toxic, low VOC, and lanolin-based chemistry designed for safer indoor use.
• Low odor helps maintain a comfortable workspace while you work.

Choosing Blaster Surface Shield means selecting a versatile protection option that can fit into your routine automotive care without disrupting your workspace or vehicle aesthetics. Consider it as part of a proactive approach to extend the life of underbody components and support reliable performance in challenging climates.
