Restoring Chalky Gelcoat: Compound vs. Wax & Oxidation Removal

Quick Verdict: Wax does not fix oxidation. If your hull looks "chalky," you must use a Rubbing Compound first to remove the dead gelcoat layer. Only apply Marine Wax after the surface is shiny to seal it.

The 3-Step Restoration Process

Searching for "boat soap" won't fix a dull hull. You need a chemical restoration.

The Gelcoat Restoration Workflow

Step Product Type Purpose
1. Strip Hull Cleaner Removes yellow waterline stains and old wax. Acid-based.
2. Cut Compound Abrasive paste that removes oxidation and scratches.
3. Protect Paste Wax Seals the pores of the gelcoat to prevent UV damage.

Work Smarter, Not Harder

Restoring a 25-foot boat by hand is impossible.

  • The Buffer: Use a Dual Action Polisher (Shurhold). Unlike a rotary buffer, it won't "burn" or swirl your gelcoat.
  • The Pads: Use Wool Pads for compounding (cutting) and Foam Pads for waxing (finishing).
