MATIC Undercoating Spray 650ml
Rubberized Undercoating Spray designed for automotive use; the product itself falls into the common category of a large-volume aerosol can for vehicle undercarriage protection.
The 650ml size is a large, common volume for professional-grade and DIY undercoating aerosol cans, often containing a rubberized or bituminous (asphalt-based) formula.
🛡️ Primary Function & Benefits
The main purpose of this spray is to create a durable, protective layer on the exposed metal parts of a vehicle's undercarriage.
- Corrosion and Rust Protection: Forms an impermeable barrier that seals out moisture, road salt, chemicals, and exhaust fumes, which are the primary causes of rust on a vehicle's frame and body panels.
- Impact Resistance: The coating is designed to be thick and flexible, protecting the metal from abrasion and impact from road debris, gravel, and small stones.
- Sound Deadening: The rubberized texture absorbs vibrations and reduces road noise, engine noise, and rattles, contributing to a quieter ride in the cabin.
- Versatility: Suitable for undercarriages, wheel wells, fenders, floor pans, and even the interior side of hoods and trunk lids.
✨ Key Features of Rubberized Undercoatings

💡 Application Tips (General)
For best results with any undercoating spray:
- Preparation is Key: The surface must be thoroughly cleaned, degreased, and completely dry. Any existing loose rust, dirt, or oil must be removed.
- Treat Existing Rust: If rust is present, it should be treated with a rust converter or removed before applying the undercoating.
- Apply Evenly: Shake the can well and apply in light, even coats, allowing sufficient time to dry between coats for maximum thickness and durability.
