BOAT MAINTENANCE

SHINE ON

Keeping a shine on the exterior of your boat is not only a matter of pride, it’s also smart maintenance.

A clean, shiny gel coat or painted finish sheds grime, salt and marine growth much better than a weather-dulled finish. It’s easier to keep clean, and it won’t deteriorate as rapidly, helping to hold the value of your boat when the time comes that you want to sell it.

Finish treatments can be broken into two categories, waxes and ceramic coatings. Waxes basically bring out the shine and protect a finish that’s already present, while ceramics add another layer or coating to the existing finish.

Whatever protection you choose, it’s a must to prep the finish first. This starts with a soap and water washdown. On new finishes, that’s all that’s needed, while on those with some age, using a very fine rubbing compound may be needed to get rid of chalking and glazing on the old paint or gelcoat. Some products include a fine rubbing compound in the wax for one-step application, easing the job, but these are generally not adequate for severely aged surfaces. Follow the manufacturer’s instructions carefully because some products can produce a surface full of swirls and dull areas if not applied correctly.

Waxes and Polishes

Many waxes for boat finishes are based on Brazilian carnauba palm wax, a natural product used to create a slick, non-stick finish. In addition to boat and auto polish, it’s also used in a wide variety of products from cosmetics to release agent for fiberglass hull molding. It’s environmentally-friendly and even used in food stuffs and pharmaceuticals. 

Other waxes are synthetics based on a mixture of chemical polymers designed to improve the sheen and resilience of vehicle paint. These are generally somewhat less shiny than carnauba wax and tend to cloud over time but may last longer.

In either case, they can bring out the shine of gel coat or paint and keep your boat new-looking much longer. A good wax job typically lasts 3 to 4 months in summer weather. In tropical conditions, reapplication three to four times a year might be needed to keep a finish in prime conditions, while twice-yearly waxing is likely to be adequate in more northerly locations.

Waxing is a simple process but just smearing on wax won’t bring a shine back to a chalky gelcoat. It takes some careful preparation, starting with a good washdown with boat soap. On a new or near-new hull, no further prep for waxing may be necessary unless you’re a real “shine-atic,” in which touch up with an automotive-style clay bar may be necessary to further smooth the finish before waxing.

On more oxidized hulls with visible chalking, “compounding” is the next step. It’s a polishing process with extremely fine cutting compounds suspended in a poly base, done either by hand or with a buffer.

The compounds are available in various levels of cut, from very mild to very aggressive—choose one that suits the condition of your hull.

Applying the compound by hand gets the job done, but it goes much faster with a buffer in the 7” to 10” size. And note that rubbing compounds come in various “cut” categories, with some of the more abrasive mixes capable of taking off some pretty serious scratches. But also be aware they can burn off your actual gelcoat as well if you use too much pressure, turn the buffer up too high or buff with the edge instead of the middle portions of the pad.
