Custom Shop Panel Prep & Degreaser — 1 Gallon Low-VOC Surface Cleaner for Auto Panels, Ready-to-Use

Custom Shop Panel Prep and Degreaser is a ready-to-use, low-VOC water-based cleaner formulated to remove oils, sanding dust, and contaminants so panels are primed for paint or primer.

This 1-gallon surface cleaner blends solvents and detergents into a low-VOC formula (<25 g/L) designed for automotive and general panel preparation. It reduces static, lifts grease and road film, and rinses without leaving residue, making it an efficient final wash before sanding or applying paint. The product works on a wide range of substrates — from bare metal and aluminum to primed or painted surfaces and many interior materials — while remaining safe for most applications when used as directed.

How does this degreaser prepare panels for painting?

The formula targets and dissolves oils, sanding dust, and other surface contaminants that interfere with adhesion. Removing those residues helps primers and topcoats bond evenly and reduces the risk of finish defects caused by trapped debris.

• Water-based blend with solvents and detergents for effective cleaning
• Removes sanding dust, road grime, and common surface oils
• Leaves no residue to block primer or paint adhesion

Can I use it on different materials like plastic, vinyl, and metal?

Yes — the product is formulated for versatility across many surfaces commonly found in auto and restoration work. It is compatible with painted or primed panels, aluminum, bare metal, plastic, vinyl, and leather, but avoid using it on lacquer finishes.

• Safe on primed and painted surfaces when used as directed
• Suitable for aluminum and bare metal preparation
• Works on interior materials such as vinyl and leather for trim cleaning

What are the environmental and application benefits of the low-VOC formula?

The product keeps VOCs under 25 g/L, reducing solvent odor and environmental impact compared with higher-VOC cleaners. The low-VOC blend also helps lower static, which improves metallic paint orientation and minimizes dust attraction during application.

• Meets low-VOC threshold for reduced emissions and smell
• Static reduction improves metallic flake alignment and finish quality
• Ready-to-use gallon eliminates measuring and mixing for faster prep

How do I apply it and what precautions should I take?

Apply the degreaser with a clean cloth, spray, or wipe across the panel and follow with a lint-free towel to remove dissolved contaminants. No mixing is required; it is supplied ready-to-use. Avoid prolonged contact with lacquer surfaces and always test in an inconspicuous area if unsure about compatibility.

• Use a clean, lint-free towel or appropriate spray/wipe method
• Wipe until surface is visibly clean and dry before sanding or painting
• Not recommended for lacquer finishes; perform spot tests as needed
