Magnet Paint MGP-UCP99-04 Chassis Saver Gray Underbody Rust Prevention Coating 1 Quart

Magnet Paint Chassis Saver is a high-solids, VOC-compliant, single-component chassis paint and underbody coating specially formulated to permanently stop automotive and truck corrosion — no primers or topcoats required. This gray finish variant provides the same industry-trusted rust-stopping protection in a neutral color ideal for frames, floorboards, engine compartments, and other underbody surfaces.

Key Features:

• No Primer Needed: Can be applied directly over tightly adhered rust after minimal surface prep with a wire brush or hand scraper to remove loose scale and particulate
• Rock-Hard, Flexible Finish: Bonds to blasted and rusty metal to form a glaze-like, non-porous film that resists cracking, chipping, flaking, and peeling
• Moisture-Cure Formula: Cures by reacting with atmospheric moisture — no hardeners or activators required — resulting in a finish comparable to a catalyzed coating
• Chemical Resistant: Completely unaffected by road salt, gasoline, diesel fuel, oils, battery acids, hydraulic fluids, solvents, and other corrosives
• VOC Compliant: High-solids, single-component formula meets VOC compliance requirements
• Versatile Application: Suitable for frames, floorboards, engine compartments, suspension components, and other underbody areas
• Gray Color Finish: Neutral gray tone for a clean, finished appearance
• Size: 1 Quart

Chassis Saver works by isolating bare and rusted metal from oxygen and moisture — the two key catalysts of corrosion. For best results, sandblasting to a medium blast profile is recommended, though the product's unique rust-stopping properties allow effective application even with minimal surface preparation.
