I have buffed my boat many times already only to have it Cleaning Gelcoat Stains come back Chalky a couple of cleaning gelcoat stains 75 later. What about paint? I suppose cleaning paint oxidation would be similar to gelcoat oxidation but could vary depending on cleaning gelcoat stains 75 specific formulation. Hope that helps and good luck with your project!

Which gelcoat cleaners are best at combating waterline yellowing on boat hulls? Ben Meakins dons his rubber gloves and puts 10 products to the test. Luckily for us, there are few more satisfying jobs than removing such stains when you use the right tools.

Instead, a chemical reaction does the job for you. Bear in mind that each time these products are used, some of the gelcoat is removed. Therefore, care should be taken to use the least aggressive product that will get the job done.

Polishes and rubbing compounds can be applied by machine or by hand. Step four: Protect the shine with a wax. Once you have polished the surface and removed the stains, it is time to seal and protect the surface with a wax. In addition to sealing out oxygen, which prevents oxidation, many waxes contain inhibitors that protect gelcoat against damaging UV light. There are several types of wax, each of which has its adherents. Choices include pure carnauba, carnauba polymer blends and polymer only formulations.

Wax, like polish can be applied by machine or by hand. Do not apply wax under direct sunlight. Aside from washing non-skid areas and possibly removing the stains, most people leave their molded-in non-skid alone. This is because they believe that polishing and waxing non-skid will make it slippery. For old, worn non-skid this may be true. But for non-skid that is in good condition, Shurhold Industries has shown that it can indeed be polished and protected without a loss of Cleaning Gelcoat Stains Question traction.

Conventional Cleaning Gelcoat Stains Years wisdom dictates that gelcoat polishing and waxing should always be performed as separate operations. While we are confident that the four-step procedure outlined above will result in a bang-up job of which you can be proud, alternatives exist.

Bucking tradition are one-step products that combine a polish with a wax. After all, why spend all day on a project when you can finish the job in half the time! There are two types of machines that you can use. The first are variable speed circular polishers, which in the hands of a pro can quickly cover a lot of ground.

Therefore, we suggest that unless you are experienced, you use a random orbital polisher. These are available with built-in rechargeable batteries and also as AC plug-in units. If you plan on using an AC machine with your boat in the water, make sure the machine is GFCI-protected, since water and electricity are a dangerous combination. Once you have finished the restoration, all you need to do is follow up with regular wash downs and periodically apply a fresh coat of wax.

When your gelcoat fades beyond recovery, paint—actually linear polyurethane—is your best friend. Yes, you can re-gelcoat, but why? LP is harder, smoother, more fade- and stain-resistant, and easier to maintain than gelcoat, explains Matt Anzardo, North American marketing manager at AkzoNobel, the parent company of Awlgrip and Interlux. The two materials are completely different, he says: Gelcoat cures via a chain-reaction initiated by a catalyst usually MEKP, the clear liquid that comes with polyester resin you buy at the chandlery.

Awlgrip, like other linear polyurethanes, is cured, not catalyzed, from components carefully mixed in a precise ratio that cross-link to form the linear polyurethane coating. The Awlgrip system includes a proprietary cleaner, Awlwash, and polymer sealant, Awlcare. Expect to get 10 or more shiny years from a properly maintained LP job.
