Buyer’s Guide

Although the wide selection of gelcoat restorers granted boaters the freedom to choose a product that meets their needs, purchasing the perfect one may be a challenging mission. To avoid spending your hard-earned money on lousy products, it is essential to conduct a thorough research. This way, you’ll be ensuring a smart investment for your watercraft.

Hopefully, with this buying guide, you can reach a commendable decision.

 Decide on a restorer that effectively brings back vibrance and shine.

You’re probably wondering how to remove oxidation from fiberglass gelcoat with just one bottle. The thing is, the effectivity of the product should be the foremost factor to consider.

Since you will be spending your money on your boat’s upkeep, make sure to purchase the best product. It should get rid of stains like light to heavy oxidation, water spots, rust, etc.

As it eliminates those nasty contaminants, it should simultaneously leave a brilliant sheen and deep color. On the contrary, making sure this specification is met may be a tough challenge. That is why you should keep yourself in check through reading gelcoat restorer reviews. In doing so, you can guarantee the best worth for your money.

Choose the one that promotes easy application.

Restoring your gelcoat takes a lot of effort and time. That is why it is always a smart idea to purchase easy-to-use products. Preferably, select the one that can be applied using a boat buffer or by hand.

Additionally, a formula that results in a noticeable shine after one application is a better choice, among others.

Choose the one that doesn’t require polishing and waxing.

Most gelcoat restorers are formulated to polish surfaces. Further, there are brands that polish and wax at the same time.

For one, the Optimum Gelcoat Restorer lets you forego polishing as it leaves your watercraft glistening under the sun. If you’re going to think deeply, this kind of investment will save you effort, money, and time.

Choose the one that lasts longer.

Ideally, you must always check how long the shine and vibrance last. If you chose to pick a cheaper alternative that only lasts for a week or two, you’d be wasting your time, money, and effort.

Keep in mind that restoring a watercraft takes hours. And you wouldn’t want to repeat this several times in one season. As for me, I always pick the one that lasts for a year. Although it may be pricier than others, it is undeniably a worthwhile investment in the long run.

Invest in a product that protects against UV damages.

As you know, boats spend most of their time under the sun. Picking a brand that leaves a protective film against sun damages allows its bright shine and color to lasts longer.

How to Restore Chalky Gelcoat

One of a boater’s joy includes upkeep their beloved watercraft’s new-like shine and color. While it is natural that gelcoat becomes chalky, old, and dull-looking, there is always a way to solve this problem. That involves restoring it with a trusted product.

To make this difficult task simple, here are a few tips for you to follow:

Wash off dirt and stains.

Before anything else, clean boat surfaces with your preferred boat wash. Avoid using dishwashing soaps as they may cause more harm to the surfaces. Once your done rinsing, let your boat dry.

If your vessel is predominantly filled with nasty stains, a heavy-duty cleaner usually does the trick. It eliminates rust, stubborn stains, bird droppings, etc. Remember to wear safety gloves and goggles to avoid eye and skin irritations.

Apply the rubbing compound on the surfaces.

This step is necessary to eliminate hard-to-remove oxidation. When compounding your boat, apply a small amount of rubbing compound unto the desired surface using a pad. If you want to get things done easier and quicker, you can use a handy polisher.

Take your time until your surface looks free from oxidation.

Polish the gelcoat surfaces.

You can forego this step if you are using a gelcoat polishing compound. Meanwhile, if you utilized a plain gelcoat restorer, the polishing step should never skip. This assures a showroom-quality shine that allows you to showcase your boat proudly. It can be applied using a boat buffer or by hand.

Seal the surfaces with a premium boat wax.

Again, boat restorer products that double as a polish and wax allows you to forego this step. However, for those meticulous boaters, applying wax is always necessary. This protects the surfaces from potential damages caused by UV rays or environmental contaminants.

Moreover, it allows your boat’s luster and shine to last longer.


Gelcoat is highly susceptible to oxidation and stains. On the bright side, this problem will go away if you have the best gelcoat restorer.

Despite that, the vast array of choices hinders boaters in making the right investment. Luckily, our product reviews aim to save you from this trouble. Likewise, the tips and information shall help you realize a more convenient answer for oxidized gelcoat restoration.
