Buyer’s Guide

best-boat-compound

While there are tons of brands claiming to be the best buffing compound for boats, not all of them stay true to their words. That is why it is always smart to delve into necessary information before making that purchase. When you do, you’ll get to ensure a profitable investment and a brighter finish for your vessels.

To assist you in finding that perfect rubbing compound, here is a brief guideline you can follow through:

Check the severity of damage on your boat’s surface.

This is the first factor to keep in mind. If your boat is infested with light oxidation, you only need a less gritty abrasive to cut through the gel coat. Meanwhile, if your vessel is severely oxidized and stained, it requires a “sandier” compound.

It is not that hard to figure out this specification. The labels already indicate the level of abrasive they possess.

There are light rubbing compounds for light oxidation stains. On the other hand, there are medium rubbing compounds for medium oxidation. Lastly, there are heavy-duty rubbing compounds made to get rid of tough and age-old oxidation and other stains.

Choose a compound that is tough on stains but gentle on the surfaces.

You need to consider this component with its effectiveness equally. Choose the right compound that is gentle on the surfaces and doesn’t leave behind unwanted scratches.

Choose the one that is easy to apply.

Formulas that stay wet longer will allow you to compound for a long time. Apart from that, it also covers more areas. This allows you to use little of the product without compromising your vessel’s overall look.

If possible, go for the one that can be applied either by hand or machine.

Choose the right thickness of the formula.

Boat compounds that are too thick tend to congest on the buffing pad. Instead of restoring your watercraft, this will cause more damage. In turn, it defeats your purpose and wastes your money on nothing.

To avoid this mess, invest in a product that has the right thickness. It shouldn’t be too thick, nor too watery.

Check the ingredients.

Rubbing compounds that contain fillers like silicone must be avoided at all costs. These harmful components leave smears on your gelcoat, thus, defeating your purpose in restoring it. Also, these useless fillers aren’t worth the money.

Invest in a pure rubbing compound.

One-step products that promise to compound, polish, and wax at the same time are a tempting solution for your boat. Unfortunately, they do not guarantee a long-lasting brilliance, sheen, and color. If you are a conscientious boat owner, you would want the best for your watercraft no matter the effort and time.

Choose a product that compounds alone. For one, the 3M gel coat compound performs aggressive yet safe cutting performance. Its potent ingredients are engineered to compound alone, thus, leaving a damage-free surface.

Afterward, you can purchase a trusty marine polish and wax that shall promote shine and safeguard your boat.

Purchase the right amount for your boating needs.

Most compounds are sold in 16-ounce, 32-ounce, and one-gallon bottles. Depending on the size of your boat, purchase the right amount to complete the job.

Go for an affordable choice.

This is the last factor that you need to consider. There are tons of affordable brands that are trusted by boating professionals for years. Although it is worthwhile to spend money on upkeeping your watercraft, you don’t need to cut off your bank account. Be the smarter boater and purchase the one that fits your budget.

Can I Use Rubbing Compound on Gelcoat or a Boat

marine-rubbing-compounds

Yes, you definitely can. If your boat is extremely weathered and oxidized, this is the prime solution. Contrary to other beliefs that it may scrape off the gel coat, it doesn’t. It only slowly cuts through the defects and eventually reveals a clear and clean slate.

Also, your vessel’s gel coat is thicker than you think it is. Hence, compounding it will never harm the surface. To keep things safer, be careful when you buff the surface. Do not put pressure on too long to achieve better results.

How to Compound a Boat

best-buffing-compound-for-boats

You are probably wondering how to remove oxidation from fiberglass boat. All you have to do is to learn the basics of compounding a boat. This skill is not only applicable to restoring your most prized vessel, but you can also utilize it in upkeeping your automobiles.

To help you relive your boat’s former glory, here are a few steps to follow:

Apply the formula.

First, apply the compound on the surface. It would be best if you worked by section. Then, put a little amount unto the wool pad before rubbing it unto the fiberglass.

Slowly buff your boat.

You can either apply it by hand or through a rotary buffer, but I suggest you use the latter. This makes things faster and easier. Remember to start at a slower speed. This gets the oxidation, chalking, and stains off the boat slowly. Buffer consistently at this speed to avoid burning the gel coat. Do it until you get a clear surface.

Also, do not expect the surface to be gleaming as you are only preparing your vessel for polishing.

Clean it up.

After the compound has dried out, it is time for the cleanup. Wipe off the surface with a cloth.

Prepare to polish and wax your boat.

When you are done clearing off the stains, oxidation, and weathering off of your vessel, it is time to polish it. This maximizes the gloss and vibrance of the surface. Afterward, you need to safeguard this new shine with reliable wax. Doing so protects the surface and makes the gloss and color last longer.

Conclusion

Hopefully, the product reviews have enlightened you in choosing the best rubbing compound for boats. Rest assured, these products are trusted to provide you with the best performance. In the same way, we included additional information and tips in compounding your boat and preparing it for polishing.

All things considered, restoring your oxidized boats to its new-like shine is not as challenging as it may sound. As long as you make the right choice, you can achieve a gleaming shine that you can proudly showcase as you travel through the waters.
