If you’re looking to improve your boat’s overall appearance and you want to tackle oxidation, then the 3M 36102 Perfect-It Gelcoat Heavy Cutting Compound is a product that you’ll want to check out. This cutting cream is specifically made for fiberglass and gel coat. It’s a great option to remove those unsightly yellow oxidation marks.

This oxidation remover comes in a white paste with a thick consistency. Unlike other cutting compounds that can be quite abrasive, this one is much more gentle. It’s recommended that you add a bit of water to get the ideal consistency.

Applying the cutting compound is simple as it can be applied by hand, air polisher, or orbital machine with a wool pad. The manufacturer recommends that you apply to a pad and then apply to the surface. Working the product into the surface can clear up the oxidation marks. You may have to work it into the surface multiple times to get the ideal results. It's part of a whole lineup of 3M products and usually you can go straight from this to the wax finish, unless you want to bring back even more of the shine. Then an extra polishing step might be needed.

Frequently Asked Questions (FAQ)

What is the best oxidation remover for boats?

Finding the best boat oxidation remover can be rough. More than a few boating enthusiasts have had to throw out a favorite boat after father time oxidized the surface and made it unappealing. So, I decided to do what I always do when I need advice. I begin by asking other people who are probably just like me.

I posted on a few boating groups about what they liked and what they didn’t like from what they had tried. I also reached out to the local pro-shop and asked the questions that I, and hopefully you, are asking.

I found that the consensus was that nothing on the market would remove the previous damage that was evident after a trail. But, added into the mix was a general consensus that for a casual boat owner who was looking to just protect their monetary investment, there were a few good options.

I then did my own research to see that I had a few of my own questions answered. You can find my results above.

How do you remove heavy oxidation from a boat?

Assuming you have been using a good wax for years, that's what weathered oxidized will look like. No matter what way you get your boat sparkling again if you use the right oxidation remover process. First use one of the oxidation removers on this list with a wool pad and then polish and wax. The three step procedure will get the shine back to your boat.

How do you restore heavily oxidized gelcoat?

This is an entire category of products, as there are a variety of products available. I see a lot of people using paint remover and that would be a poor choice for your boat because of the harsh chemicals.

The key is to get in and get it done quickly. Do a light scrub after using a product like this and then rinse well. Repeat if needed.

How do you remove oxidation from boat gelcoat?

Do you have oxidation on your boat? This can be a problem on fiberglass or composite boat hulls. There is some good news: it doesn’t have to stay there. You actually have several different options for removing oxidation from boats.

The first step is to determine what sort of oxidation you have. This can be difficult without professional equipment, but there are usually two possible causes.

It’s frequently either a thin layer of oxidation that forms in the first place (surface oxidation) or a buildup from the gelcoat underneath burning away. If the oxidation is thin, it will usually only be a few millimeters deep. In that case, you may not need a heavy-duty deoxidizer to remove the oxidation. A cleaning sponge and some soap or detergent should do the trick. Just make sure that you are focusing on the areas where the oxidation has occurred.

Conclusion

A boat is supposed to stay in water and be used. However, this also leads to some signs of wear like oxidation. Once the boat is taken out of the water and stored for long periods, oxidation sets in and ruins the boat.

How do you reduce this damage? Well, you could just leave the boat in water all year, but that could be a bad idea.

So, it’s best for you to invest in an anti-oxidation boat treatment. Here are the best powerboat and pontoon boat oxidation removers in the market at this moment.
