Importance Of Waxing Fiberglass RV

Waxing your fiberglass RV is crucial to protect it from the damaging effects of UV rays, prevent deterioration and restore its shine and appearance.

Protection From UV Rays

Taking good care of your fiberglass RV involves protecting it from the harmful effects of UV rays. Just like our skin, prolonged exposure to sunlight can cause significant damage to an RV’s exterior finish and lead to unwanted consequences, such as fading, chalking, and even cracking.

To provide optimal protection against UV rays, selecting a high-quality wax with added UV inhibitors is essential. These specialized waxes form a protective barrier on the surface which reflects the sun’s ultraviolet light instead of allowing it to penetrate into the gel coat.

This not only helps maintain your RV’s glossy appearance but also ensures its longevity by preventing deterioration caused by harsh environmental factors.

Prevention Of Damage And Deterioration

As RV enthusiasts, we all know how important it is to protect our investment and prevent damage and deterioration. Fiberglass RVs are particularly vulnerable to wear and tear due to their exposure to the elements, including UV rays, road debris, and weather conditions.

To maintain the beauty and durability of your fiberglass RV, it’s crucial to take preventative measures such as regular cleaning and waxing. Not only will waxing help restore the shine of your RV’s exterior finish; it also acts as a protective barrier against potential damage from environmental factors.

Restoration Of Shine And Appearance

Restoring the shine and appearance of your fiberglass RV is crucial in maintaining its overall value, quality, and aesthetic appeal. Regular waxing can help bring back the luster and vibrancy of its exterior finish while protecting it from damage caused by exposure to the elements.

Applying a high-quality marine or fiberglass wax after thorough cleaning can effectively restore your RV’s gel coat finish. This will also protect it from future oxidation, discoloration, and fading caused by UV rays from the sun.

By working on small sections at a time using gentle or medium pressure with an applicable tool, you can ensure that every inch is covered evenly for maximum shine and durability.

In all cases for maximum effect; it’s important to be consistent with regular waxing sessions throughout the year.

21 Tips For Waxing Fiberglass RV

Here are some tips to follow when waxing your fiberglass RV: Clean the surface thoroughly before applying wax, use a high-quality marine or fiberglass wax, work in small sections, apply multiple coats regularly and avoid direct sunlight.

Proper Cleaning And Preparation

Before waxing your fiberglass RV, it is essential to clean and prepare the surface properly. Any dirt or grime on the surface can lead to scratches and damage during the waxing process.

Start by using a high-quality car wash shampoo such as Gel-Gloss RV Wash and Wax to gently remove any dirt or debris from the surface.

In addition to cleaning, it is also important to check for any cracks or damage in the fiberglass that may require repairs. Waxing over damaged areas can worsen the problem and cause more extensive damage down the road.

It’s always best to repair any damages first before applying wax for optimal protection and shine.

Use Of High-quality Wax And Applicator

Using a high-quality wax and an appropriate applicator is crucial to achieving optimal results when waxing your fiberglass RV. A marine or fiberglass wax will provide the best protection against environmental factors such as UV rays, water damage, and corrosion.

Choosing a proper applicator such as a foam pad or microfiber cloth will ensure even coverage across all surfaces of your RV and minimize the risk of scratches or damage during application.

It is important to follow manufacturer’s instructions for both the wax and applicator to achieve maximum durability and shine.

Work In Small Sections

To ensure an even and thorough waxing job, it’s important to work in small sections of your fiberglass RV. This allows you to focus on one area at a time, ensuring that you don’t miss any spots or apply too much wax in one area.

Instead, start by cleaning the section thoroughly before applying your high-quality marine or fiberglass wax using a surface applicator. Use circular motions to spread the wax evenly across each small section before buffing with a clean microfiber cloth for optimal shine and durability.

Avoid Direct Sunlight And Excessive Pressure

When waxing your fiberglass RV, it is important to avoid working under direct sunlight or applying excessive pressure during the process. Direct sunlight can cause the wax to dry too quickly and leave streaks behind, while excessive pressure can damage the delicate gelcoat finish.

Instead, work in small sections at a time and use a gentle touch when applying the wax. Additionally, make sure to use high-quality products specifically designed for fibreglass RVs and follow manufacturer instructions carefully.

Apply Multiple Coats Regularly

Another important tip for maintaining the shine and durability of your fiberglass RV is to apply multiple coats of wax regularly. This will help protect the RV from UV rays, water damage, and corrosion.

When applying multiple coats, make sure each layer is dry before applying another one. This ensures that each coat adheres properly and provides optimal protection.

By following this tip along with other maintenance tips like proper cleaning techniques and avoiding harsh chemicals, you can keep your fiberglass RV looking great for years to come.

Use Of Protective Covers And Storage Under Shelter

To protect your fiberglass RV from environmental damage, it’s essential to store it under a protective cover or in a sheltered area. When left exposed to the elements, the paint and gelcoat can deteriorate quickly due to exposure to UV rays and other harmful external factors that could compromise the structural integrity of the RV.

In addition, using specialty products like wax sealants can also provide an added layer of protection against water damage and corrosion.

Applying these coatings periodically throughout the year is crucial for keeping your RV’s finish looking glossy while also preserving it against deterioration over time.

Avoid Harsh Chemicals And Use Of Specialized Products

As much as possible, it is best to avoid using harsh chemicals and specialized products when cleaning your fiberglass RV. These types of products can damage the surface, causing it to become more porous and prone to oxidation.

It’s always better to stick with gentle rubbing compounds and high-quality marine or fiberglass wax. Not only are these options safer for your RV’s exterior, but they also provide optimal shine and durability without causing any harm.

Seek Professional Help And Follow Manufacturer’s Instructions

It’s always a good idea to seek professional help when it comes to maintaining your fiberglass RV. They can provide valuable advice on the best products and techniques for protecting and preserving your vehicle.

For instance, if you have a certain type of gelcoat finish, there may be specialized waxes or sealers that work best with that specific material. By consulting with an expert or reading through your RV owner’s manual, you can avoid accidentally damaging your vehicle while trying to keep it looking its best.


In conclusion, maintaining the shine and durability of your fiberglass RV requires regular waxing. By following the 21 tips provided in this article, you can protect your RV from UV rays, damage, and deterioration.

Remember to use high-quality products and applicators, work in small sections, avoid direct sunlight and excessive pressure, and seek professional help when needed.
