Klean-Strip Prep-All (GSW362) is a professional wax & grease remover formulated to prepare surfaces for primer and paint by removing contaminants that interfere with adhesion. It’s used by body shops and DIYers to guarantee a clean, residue-free surface prior to refinishing.
Features — explainedRemoves wax, grease & silicone: Prep-All dissolves and lifts wax, grease, silicone residues and other film contaminants that block primer/paint adhesion. This prevents future peeling, fisheye, or adhesion failure.
Fast-drying, residue-free: The formula evaporates quickly without leaving oily residues when used per instructions — leaving a surface that paint can grip to immediately.
Safe on multiple substrates: Effective on metal, painted surfaces, plastic trim and fiberglass when used as directed. However, always test on an inconspicuous area first (see Usage: Compatibility check).
Professional size: The 1-gallon container is ideal for body shops, fleets and serious DIYers — economical for multiple prep jobs.
Specifications & Practical CapacityEstimated (real world): ~200–400 sq ft per gallon when used for general wipe-down prep (one pass) — coverage varies greatly by contamination level and application method. Heavy soiling or multiple parts will reduce yield; small spot cleaning uses far less.
Shop guidance: For complete vehicle prep expect to use ~1/2 to 1 gallon for a small car (panels, doors, trunk lid) depending on how dirty surfaces are.
Usage Method — Step by StepPrep-All contains solvents. Use in a well-ventilated area. Wear chemical-resistant gloves and eye protection. Avoid inhalation of vapors; if ventilation is poor, use an appropriate respirator. Keep away from heat, sparks and open flame. Store in a cool, dry place in the original tightly closed container. Dispose of rags used with solvents safely; they can be a fire hazard.
Quick FAQCan I dilute Prep-All? — No. Use full strength as directed for effective wax/silicone removal.
Can I use on painted surfaces? — Yes, for preparation before painting, but test first on sensitive clearcoats or older paints.
