ProductionShop GWR440 Automotive Grease and Wax Remover — Fast‑Evaporating Paint Prep Cleaner for Metal, Plastic & Fiberglass

ProductionShop GWR440 is a fast-acting grease and wax remover formulated to dissolve and lift contaminants like wax, tar, adhesive residue, and tree sap so painted surfaces are clean and ready for bodywork or painting.

Before any paint or body repair, surface cleanliness determines adhesion and final finish quality. GWR440 targets common contaminants that compromise paint bond, working on painted metal, plastic, epoxy, and fiberglass. It evaporates quickly without leaving a film when used as directed, helping technicians move from sanding to primer or topcoat with confidence.

How does GWR440 prepare surfaces for painting?

GWR440 breaks down and loosens soils rather than just smearing them across the panel, enabling effective removal with lint-free cloths. Use a separate saturated cloth to apply and a separate dry cloth to remove contaminants to avoid re-depositing residues.

• Dissolves grease, wax, tar, adhesive residue, tree sap, silicones and light oils.
• Works after sanding to remove dust-bound contaminants and residues.
• Evaporates quickly to reduce downtime before primer or topcoat application.

What surfaces and applications are suitable for this product?

GWR440 is formulated for automotive and industrial paint prep across multiple substrates. It is safe for painted finishes, metal, plastic, epoxy, and fiberglass when used according to instructions.

• Ideal for panels, bumpers, trim, and composite body parts.
• Use before masking, priming, or topcoating to maximize adhesion.
• Works well as an anti-static panel wipe prior to painting.

How should professionals apply GWR440 for best results?

Follow a two-cloth method: saturate one clean, lint-free cloth for application and a second clean cloth to remove dissolved contaminants. Replace cloths frequently and avoid circular rubbing that could redistribute residue.

• Apply in a well-ventilated area and test an inconspicuous spot if unsure.
• Use a wet cloth for application and a dry removal cloth; change often.
• Allow the surface to flash briefly—no visible residue should remain before painting.

Will GWR440 leave any residues or affect paint adhesion?

When used properly GWR440 evaporates and does not leave a film that interferes with adhesion. It is designed to remove contamination that would otherwise prevent proper bonding of primers and topcoats.

• Formulated to dry quickly with no residue when wiped away correctly.
• Promotes consistent paint adhesion by removing adhesion-inhibiting contaminants.
• Not intended for use as a long-term cleaner—use immediately prior to coating operations.
