Best Rubbing Compound for Boat Reviews

1. 3M Marine Rubbing Compound

3m marine rubbing compound

The 3M marine super duty rubbing compound is widely suggested as an effective substance to treat heavy oxidation that has been too stubborn. It is capable of reliving even an aggressive surface, such as marine paint and oxidized gel coat, to restore the impressive appearance of your boat from the beginning.

Its premium formula is a fast-cutting one with no wax or silicone included to ensure the best rubbing performance on your sea transportation. Plus, this white compound can be buffed to achieve an appealing high gloss finish but still minimizes the number of possible swirl marks left after completing the job.

In addition, this substance will cling on better to painted and gel-coated boat surfaces as to create the least amount of mess. Since it consistently remains wet during your boat rubbing process, there is much less interruption. You should combine it with the 3M Marine Finesse-It II Glaze for the finest results.

Many people have praised the amazing longevity of this marine rubbing liquid, so you can put it to storage with peace of mind if the bottle hasn’t been used up yet. It is suitable for restoring mineral deposits, especially boat rusting, or cleaning light-colored boat fenders to give them back the initial luxurious look.

Although the compound is pure white, you may notice that it is likely to leave behind a rather brownish hue to the boat paint after the job. This issue is hard to explain because I believe its description states clearly as a completely white paste, without any extra color added to the substance for such a final shade.

What We Like
  • Treats aggressive, stubborn oxidation
  • Fast-cutting formula and glossy finish
  • Remains wet in use for the least mess
  • Ensures great longevity for storage
What We Don’t Like
  • May leave a brown hue post-applied

The 3M Marine Rubbing Compound is an optimal combination of what you need to eliminate stubborn oxidation and return the attractive look with a high gloss finish to your boat. Because this substance can maintain its wetness in use, there will be fewer problems relating to a paste that dries out too soon.

2. STAR BRITE Liquid Rubbing Compound

There are two restoration levels of medium and heavy oxidation for this liquid rubbing compound by STAR BRITE. It is a high-quality substance for stains, scratches, and oxidation treatment on your favorite boat. This bottle should be one of your top choices when it comes to restoring the original boat shine and colors.

It is your choice whether to apply the substance by hand or with a buffer for the best outcome. This liquid rubbing formula performs really well on painted, fiberglass, and metal surfaces. Therefore, it can work as a useful restoration on any objects that contain such surfaces, for example, tabletops and cars.

You only need to use the restoration compound sparingly on your marine boat because a little manages to go a long way to bring back the initial shiny look. Since this substance does not require setting up like most other products on the market, it is quicker and easier to be removed from the applied surfaces.

In terms of the perfect follow-up for this boat compound, I would recommend the Premium Marine Polish from the same manufacturer. This extra support is responsible for maintaining the restored surface finish done by your bottle of compound. That way, it will not be affected by multiple impacts on the outside.

However, I see that the item may cause a loss of your desired vibrancy on a fiberglass surface. It does give the boat a shiny finish but in the end, I feel like it leaves me with a feeling of simply adding another coat of wax on fiberglass. You might want to try swiping all leftover hulls before applying the compound.

What We Like
  • Perfect for restoring shine and colors
  • Works on a wide range of surfaces
  • Can be removed easily and quickly
  • Best combined with a follow-up polish
What We Don’t Like
  • Causes a vibrancy loss on fiberglass

When it comes to the shine and color restoration of a surface, the STAR BRITE liquid rubbing compound would be an inexpensive and reliable choice to work with. While the substance removal is always the most troublesome for many other boat compounds, this item is clearly a relief being easily removed.

3. Meguiar’s M8532 Mirror Glaze Diamond Cut Compound

This auto compound named M8532 Mirror Glaze from Meguiar’s provides a heavy fast-cutting with minimal swirls created during the procedure. It is made to meet the standards of a professional-level substance by undergoing strict successful testing in production shops, thus, you could rely on it for rubbing.

Although the boat rubbing compound delivers a great amount of thickness in use, its high-quality formula is low on dusting and splatter for easier cleaning afterward. It is important to have this kind of formula for your compound since you will require as little dust and splashing as possible while rubbing the boat.

The powerful marine rubbing compound offers 2 capacities including 32 ounces and a gallon. In my opinion, you should try the smaller capacity first before purchasing 1 whole gallon for a better warranty of its quality. It is ideal to apply this liquid using a rotary buffer, and it promises to be safe for body shops.

You will see that it has the ability to perform well on all transparent coats, even the high solids, enamels, lacquers, refinished, and glossy painted surfaces. It can remove the most severe types of defection such as acid rain, scratches, sanding marks, heavy swirls, and holograms on all of the mentioned surfaces.

In contrast to most beliefs about the benefits of a quick-drying feature in such liquid, this compound tends to dry up too quickly and results in a challenging removal from the applied surface. I think the manufacturer should reconsider changing its formula a little bit to support users better in removing this product.

What We Like
  • Exceeds the professional standards
  • Low both on dusting and splatter
  • Offers 2 different container capacity
  • Works well on multiple coat types
What We Don’t Like
  • Dries too quickly for easy removal

If the Meguiar’s M8532 Mirror Glaze Compound 2.0 remains wet for a longer time during an application, I can assure you that it will receive more attention. Since most of its advantages are beneficial such as professional standards or being low-dust, this detail will complete the substance and perfect it in the long run.

You can see that apart from marine boats, it is suitable for trailers, cars, trucks, and RVs, etc. as long as the surfaces are compatible.

This product is the most excellent rubbing remedy to solve your situation of reliving tired, scratched surfaces, especially to restore badly weather finishes than other shallow, one-step substances. It performs quite impressively for most users that need a thorough fiberglass or gel coat polishing compound.

The liquid enables a powerful elimination of 600/800 micro-fine wet sanding scratches, heavy oxidation, and swirl marks from common surfaces that easily get chalky and faded over time, like a painted, fiberglass, or gel coat one as mentioned earlier. Its aggressive fast-cutting formula works smoothly through them.

According to my experience, it is best to apply this rubbing substance with a variable-speed buffer that contains a wool compounding pad. If not, a bare hand application is also a good option. This substance remains wet enough in the rubbing procedure for easy removal later on, and it does not leave any film behind.

However, some previous users have reported that the rubbing compound may gum up the wool pad of your buffer and is actually not so easy to use. In my opinion, using rubbing compounds for boats is definitely not complicated. So if this item has been said to make things more difficult, it should be adjusted.

What We Like
  • Compatible with many vehicle types
  • Ideal to restore badly weather finishes
  • Gets rid of flaws on different surfaces

As the item’s formula can work on double tasks of a compound and polish in one easy step, it will save you a serious amount of time for using one single bottle for 2 jobs.

This powerful substance treats boat and RV oxidation on different levels from light to heavy and refreshes their exteriors to reach a whole new level. It can remove scratches and swirl marks on your marine boat surface as well, with a fast-cutting formula to reduce action time for both compounding and polishing tasks.

From my perspective, you should combine this marine rubbing substance and finishing polish with an electric buffer that contains a wool compounding pad. That way, the scratch and oxidation removal process on your boat will become much more hassle-free even for a brand new user to handle and restore the surface.

As I have mentioned earlier, choosing the smallest container capacity would always be a wise decision when purchasing a new product. That is why even when the rubbing compound offers 3 different bottle sizes of 32 fluid ounce, 1 gallon, and 5 gallon, it is best for you to select the smallest to try it out first.

This problem is not common around its previous users but you may receive a rubbing compound for boats in an awful packaging. The container cap is not securely attached and may spill out its inner liquid in the box. Therefore, you should check for this downside and report to the customer service as soon as possible.
