TotalBoat Dewaxer & Surface Prep Solvent Wash for Marine Paint and Varnish, 128 fl oz — Removes Wax and Grease for Better Adhesion

TotalBoat Dewaxer & Surface Prep is a solvent wash that removes wax, grease, and release agents so paint, varnish, and adhesives bond cleanly to marine surfaces.

Before applying bottom paint, topside coatings, primers, or adhesives, a clean substrate is essential. TotalBoat Dewaxer & Surface Prep is formulated to strip contaminates from fiberglass, gelcoat, metal, and wood, improving adhesion and reducing finish failures. It also serves as a fast solvent cleaner for brushes, rollers, and tools, and is made in the USA in quart and gallon sizes for workshop or dockside use.

How does this product improve paint and varnish adhesion?

Contaminants such as release agents, wax residues, oils, and fine dust prevent coatings from forming a uniform bond. By dissolving and lifting those residues, the dewaxer creates a dry, receptive surface for primers and topcoats, which helps coatings cure evenly and stick where intended.

• Removes release agents and waxy films left from mold or manufacturing
• Dissolves oils, grease, and silicone-based residues that repel paint
• Leaves a clean surface profile for primers, paints, and adhesives to adhere

Which materials can I safely use TotalBoat Dewaxer on?

This solvent wash was developed for common marine substrates and is effective on both rigid and soft surfaces. It is suitable for fiberglass and gelcoat as well as metals and wood, but always test an inconspicuous area first and follow safety instructions for sensitive finishes.

• Fiberglass and gelcoat surfaces for boats and hull repairs
• Stainless steel, bronze, and aluminum hardware and fittings
• Sealed or bare wood where coatings will be applied afterward

How should I apply the dewaxer for best results?

Application is straightforward: apply the solvent, agitate or wipe to dissolve contaminants, and dry the surface before coating. Work in a well-ventilated area, use appropriate PPE, and follow product label directions for dwell time and disposal.

• Apply with a clean rag, brush, or low-lint cloth; avoid puddling
• Work in small sections; wipe until no residue transfers to the cloth
• Allow solvent to evaporate fully before sanding or painting

Can I use it to clean tools and gear?

Yes — the formulation doubles as a tool and equipment cleaner, quickly removing uncured paint, grease, and adhesives from brushes, rollers, and metal parts. Rinse or wipe tools thoroughly and let them dry before reuse.

• Cleans brushes and rollers after using oil- and solvent-based products
• Degreases metal fittings and fasteners before reinstallation
• Works as a prep step for adhesive applications and repair work
