Custom Shop Bedliner Application Gun with Regulator — 1 L Bottle Compatible, Adjustable Texture Control

Custom Coat's Professional Bedliner Application Gun with Regulator is a high-performance spray gun designed to apply truck bed liner coatings evenly, with adjustable texture control and an integrated air regulator for consistent results. Built for body shops, DIY truck owners, and coating professionals, this gun accepts most 1 L bottles (including U-Pol), supports both fine and coarse spray patterns, and includes a pressure regulator that helps you dial in the ideal atomization. Its 1/4" NPS air inlet accepts typical shop compressors and operates in a wide working range to handle thicker bedliner compounds while maintaining control.

How does this gun make bedliner spraying easier?

The gun’s regulator stabilizes inlet pressure to reduce inconsistent pumping and splatter, while the nozzle and cup fitment let you switch between fine and coarse textures quickly. Ergonomics and bottle compatibility minimize interruptions during long coats.

• Built-in air pressure regulator for steady output
• Compatible with most 1 L bottles, including U-Pol
• Adjustable spray pattern for smooth or textured finishes
• Robust construction for extended workshop use

What range of air pressure and fittings does it need?

The gun uses a 1/4" NPS air inlet and runs effectively between 3–8 bar (45–120 psi) for normal spray operations, with a safe maximum pressure rating of 10 bar (150 psi). That range covers the common outputs of standard compressors used in automotive shops and home garages.

• Air inlet: 1/4" NPS standard connection
• Working pressure: 3–8 bar (45–120 psi)
• Maximum rated pressure: 10 bar (150 psi)
• Regulator enables fine-tuning at the tool, avoiding frequent compressor adjustments

Can it spray different textures and product viscosities?

Yes — the adjustable nozzle and control settings let you achieve both fine atomization for smoother finishes and coarser patterns for textured bedliner looks. It handles typical bedliner viscosities when used within the recommended pressure range and with proper thinning if required by the coating maker.

• Switch between fine and coarse sprays without tool changes
• Works with heavier bedliner materials when pressure is increased appropriately
• Fits common 1 L applicator bottles to reduce refills and downtime

What accessories or maintenance should you expect?

Routine cleaning after each use is important to prevent clogging from thick coatings; the gun’s bottle and nozzle should be flushed with the recommended solvent. Keep an inline filter and proper wrench set handy to remove and service fittings quickly.

• Flush nozzle and bottle after every use with appropriate solvent
• Inspect and replace seals if leakage occurs
• Use an inline air filter to prevent particulate contamination
• Store dry and capped to extend seal and regulator life

Who is this for? This Custom Coat gun is aimed at automotive professionals, collision shops, and experienced DIYers who need consistent, repeatable bedliner application without investing in large-scale spray equipment. If you frequently apply truck bed coatings, want control over texture and finish, and use standard 1 L applicator bottles, this gun provides a durable, workshop-ready solution that balances portability with professional features.

FAQ

Q: Is this gun compatible with U-Pol 1 L bottles?

A: Yes. The applicator gun fits most 1 L bottles, including U-Pol, allowing direct attachment and fewer refills.

Q: What air pressure should I use for textured bedliner?

A: Start around 45–60 psi (3–4 bar) and increase within 45–120 psi (3–8 bar) to achieve coarser texture, adjusting to product viscosity.
