Blaster Surface Shield Black automotive undercoating — 1 Gallon pail, lanolin-based rust protection, flexible non-peeling finish

Blaster Surface Shield Black is a professional, lanolin-based automotive undercoating that provides up to two years of moisture-wicking rust protection in a black, non-peeling finish.

This one-gallon pail from Blaster delivers heavy-duty corrosion resistance for vehicle underbodies, chassis components, and metal equipment. The Black Series formulation hides surface imperfections while forming a durable, flexible film that resists high-pressure washing and stays tack-free without cracking or flaking. Designed for spray or pour application, the thinner formula spreads easily and includes a mild cedar scent to reduce strong solvent odors during use.

How long will this undercoating protect metal parts?

Blaster Surface Shield Black is engineered to offer extended protection against rust and corrosion, with performance rated up to two years under normal driving and environmental conditions. The lanolin-based chemistry repels moisture and bonds to metal, helping prevent oxidation longer than typical industry products.

• Protective duration: up to 2 years under typical exposure.
• Moisture-wicking action reduces trapped water on treated surfaces.
• Bonding formula minimizes under-film corrosion and seepage.

Will it stay put during high-pressure washing or harsh weather?

Yes — the Black Series cures to a flexible, durable coating that resists peeling, sagging, or cracking, even when exposed to high-pressure water and variable temperatures. The finish remains intact through routine washes and road conditions when applied per instructions.

• Resists high-pressure washing and routine cleaning.
• Elastic film reduces cracking from vibration or impacts.
• Non-flaking surface maintains appearance and protection.

How do I apply this product to get professional results?

Blaster Surface Shield Black is formulated for both spraying and pouring, so you can choose the method that suits your workspace and equipment. For best adhesion and coverage, clean and degrease metal, remove loose rust, apply evenly, and allow proper cure time before road exposure.

• Preparation: remove loose rust, dirt, and oils for best adhesion.
• Application: compatible with conventional spray equipment or pouring for seams and cavities.
• Curing: follow manufacturer guidelines for dry time before use or reassembly.

What surfaces and vehicles can I use this on safely?

The lanolin-based formula is safe for most metal parts, moving components, and vehicle undercarriages. It’s suitable for cars, trucks, crossovers, electric vehicles, trailers, agricultural equipment, and industrial metalwork that needs long-lasting moisture protection without stiffening moving parts.

• Safe on metal panels, frame rails, suspension parts, and equipment.
• Won’t harm moving parts when applied correctly and sparingly.
• Recommended for passenger vehicles, light trucks, EVs, and off-road gear.
