Al’s Liner Vinyl Flattener – Matte & Semi-Gloss Coating Additive

Custom Finish. Maximum Hardness. Built for Automotive.

Ideal for Truck Beds, Interior Panels, and Exterior Automotive Surfaces

Al’s Liner Vinyl Flattener is a professional-grade coating additive that gives you precise control over sheen level while significantly increasing the hardness of your liner material. Whether you’re shooting a matte finish on an interior panel or a semi-gloss on a truck bed, this additive delivers a clean, non-reflective result that holds up to daily automotive abuse.

Designed for shops and automotive upfitters who demand more than a standard bedliner finish, the Vinyl Flattener integrates seamlessly into Al’s Liner systems for both interior and exterior applications — no compromise on protection, just a better-looking, harder-wearing result.

Perfect for:

• Truck bed liners requiring a matte or low-gloss finish
• Interior cargo areas, van floors, and panel coatings
• Exterior automotive surfaces needing a non-reflective protective coat
• Custom automotive builds where finish aesthetics matter
• Fleet vehicles and work trucks requiring durable, hard-wearing coatings

Application Note: Mix Vinyl Flattener directly into your Al’s Liner material to achieve your desired sheen level. Test on a sample panel to dial in the finish before full application.
