Gel Coat Oxidation on Boats: How to Tell, and How It Is Fixed
What gel coat oxidation looks like, why boats on the Jersey Shore oxidize, and how professional polishing and compounding restore the finish.
If your boat's hull feels chalky and leaves a white residue on your hand, it is oxidized. Gel coat oxidation is extremely common on boats kept on Barnegat Bay, the Manasquan River and the ocean, and it gets worse every season it is left untreated.
What causes oxidation?
Gel coat is porous. Strong sun, salt water and humidity slowly break down the surface, leaving it dull, faded and rough. Darker hulls show it fastest.
How bad is it?
- Light oxidation: the gloss is gone and colors look faded, but there is no heavy chalk. Usually recoverable with a single polishing step.
- Heavy oxidation: a chalky film rubs off on your hand, and colored hulls look washed out. This needs compounding and multiple passes.
How we fix it
- One-Step Polish + Wax ($45/ft, $900 minimum): wash, decontamination, one-step machine polish to restore gloss and light oxidation, then marine wax or sealant.
- Heavy Oxidation Correction + Protection ($65/ft, $1,300 minimum): compounding, polishing and surface prep, followed by durable marine protection, with as many passes as required.
Severe oxidation and yachts need an inspection before we confirm the final price.
Keep it from coming back
After correction, protection is everything. A hand wax or sealant protects for the season, and a marine ceramic coating (from $95/ft) offers premium, longer-lasting protection and easier washing. Regular maintenance washes help too.
