Dupli-Color Prep Grease And Wax Remover
Dupli-Color’s Prep Spray is designed to prime surfaces by removing oil, wax, grease, and other contaminants from metal substrates before painting. This prep step helps achieve a uniform finish and better adhesion for subsequent primer layers. The formula is solvent-borne and fast-drying, which minimizes downtime between surface preparation and painting.
- Removes oil, wax, grease and other contaminants from metal surfaces
- Maximizes gloss and finish by improving primer adhesion
- Solvent-borne, fast-drying formula for quick recoat times
To use, apply evenly to the surface, allow it to flash off, and wipe away any residue before applying primer or topcoat. Proper ventilation and PPE are recommended due to solvent-based composition.
Max Strip Painter’s Prep
Max Strip Painter’s Prep is a versatile, ready-to-use pre-painting cleaner designed to remove grease, dirt, grime, adhesive residues, and paint splashes from various substrates. It is formulated as a no-rinse solution, which streamlines the prep process and reduces handling time when working on multiple panels or surfaces.
- Multi-purpose cleaner for pre-painting surface prep
- No-rinse formula simplifies workflow
- Improves paint adhesion by thoroughly cleaning and degreasing
Apply to the surface, wipe as needed, and allow to dry before sanding or priming. Its broad substrate compatibility makes it suitable for automotive panels and other prep tasks in mixed-material projects.
Nanoskin Spot Remover
Nanoskin Spot Remover is a professional-grade surface prep product that quickly dissolves baked-on grease, road tar, silicone, wax, and adhesive. It wipes clean without leaving oily residue, ensuring panels are perfectly prepped for paint, vinyl wrap, ceramic coating, or body filler adhesion. A fast-flash formula reduces booth cycle times and helps keep masking edges crisp.
- Dissolves baked-on grease, tar, silicone, wax, and adhesive
- Fast-evaporating, reduces prep time and booth cycles
- Compliant with VOC regulations for automotive refinishing
Users should follow safety guidelines, use appropriate PPE, and ventilate the workspace, as with any solvent-based cleaner. This product is designed to deliver thorough cleaning while supporting certification and emissions compliance in professional shops.
Klean-Strip Prep-All
Klean-Strip Prep-All is a fast-acting degreaser designed to remove wax, grease, and road film from a range of surfaces, including metal, plastic, and fiberglass. It’s versatile for automotive DIY projects and prepared surfaces before painting. The formula emphasizes quick cleaning with strong grease-cutting power while maintaining safety for common substrates.
- Fast and effective wax, grease, and road film removal
- Versatile on metal, plastic, and fiberglass
- formulated with surface safety in mind; test area first for compatibility
Before use, test on a small area if the substrate is delicate. After cleaning, rinse or wipe as recommended by the manufacturer and proceed with priming or painting as soon as surfaces are dry.
Custom Shop Panel Prep Degreaser
Custom Shop Panel Prep Degreaser is a unique, water-based formula that combines solvents and detergents to cut through surface contaminants prior to sanding or applying automotive paint or primer. It comes ready to use in a one-gallon container with a low VOC profile. The product helps minimize static and dust contamination, while delivering strong grease-cutting power across primed or painted surfaces, as well as leather, vinyl, plastic, aluminum, and bare metal.
- Low VOC, water-based formula for reduced emissions
- Multi-surface compatibility including leather, vinyl, plastic, and bare metal
- Strong degreasing action with solvent support for robust cleaning
Always test on a small area first to confirm compatibility with the specific substrate. After application, wipe away residues and allow surfaces to dry before painting or priming.
Buying Guide
When selecting a degreaser for paint prep, several factors influence performance and finish quality. The right choice depends on your project type, the substrate, and the painting environment. This guide outlines key considerations and practical recommendations to help you compare products effectively.
- Surface compatibility: Choose a degreaser that works on your primary substrates (metal, plastic, fiberglass, painted surfaces). Some cleaners are broad-spectrum, while others are optimized for automotive panels or interior wood and cabinetry.
- Solvent-based vs. water-based: Solvent-based formulas often deliver faster cleaning and better wax/grease dissolution but may require more ventilation and PPE. Water-based options tend to be lower in odor and easier to manage in enclosed spaces but may need longer dwell times or rinsing.
- No-rinse vs rinse: No-rinse products can streamline workflow, especially on multiple panels or large projects. If a no-rinse formula is not available, plan for wiping and optional rinsing to remove residues.
- Drying and flash time: Fast-drying products reduce overall project time and minimize dust and contamination interference. Check cure times and ensure the surface is dry before priming.
- VOC compliance and environmental impact: For shops with emissions considerations or near open waterways, lower-VOC or VOC-compliant products help maintain regulatory compliance and sustainable practices.
- Residue and compatibility with primers: The cleaner should leave a clean, residue-free surface that promotes primer adhesion. Some products may require wiping or light scuffing after use.
- Safety and PPE: Always follow label directions for ventilation, gloves, and eye protection. Some degreasers can irritate skin or eyes, and flammable solvents require careful handling.
- Application method: Consider whether you prefer spray-on, wipe-down, or a combination. Sprays can cover large areas quickly, while wipes provide control on intricate shapes.
- Project type and environment: Automotive refinishing might prioritize fast drying and VOC compliance, while DIY home improvements may value low odor and broad material compatibility.
In practice, automotive prep often benefits from a combination approach: a solvent-based, fast-drying degreaser for initial cleansing (to remove oils and lubricants), followed by a wipe-down with a clean cloth to ensure a residue-free surface before primer. For interiors or wood/painted cabinetry, a no-rinse cleaner with low odor and low VOC characteristics can streamline the workflow without compromising adhesion. Always test a small area when introducing a new product to a substrate to verify compatibility and finish quality.
