PPG Duraprep 788 – Solvent-Based Surface Cleaner for Maximum Adhesion

Professional Wax & Grease Remover Before Priming and Topcoating

The Critical Prep Step That Makes Every Coating Perform

PPG Duraprep 788 is a high-strength, solvent-based wax and grease remover engineered to thoroughly clean surfaces before priming, sealing, or topcoating. Contaminants like wax, silicone, oil, and road film are invisible to the eye but devastating to coating adhesion — Duraprep 788 eliminates them completely, giving your coating system the clean foundation it needs to bond and perform.

Trusted by coating professionals, Duraprep 788 is the go-to pre-application cleaner for metal, painted, and primed substrates where surface integrity and adhesion are non-negotiable.

• Removes wax, grease & silicone — eliminates hidden contaminants that cause adhesion failure, fisheye, and delamination
• Solvent-based strength — penetrates and lifts stubborn oils, road film, and surface residues standard cleaners miss
• Maximizes coating adhesion — prepares the substrate for a strong, lasting bond with primers and topcoats
• Reduces surface defects — prevents cratering, fisheye, and peeling caused by contaminated surfaces
• Fast-evaporating formula — cleans quickly and leaves no residue, so you can move straight to priming or coating
• Protects your coating investment — proper prep with Duraprep 788 extends the life and performance of every coat applied
