Why Do You Need RV Wax?

Now that you know what an RV wax is as well as what the main variants are, let’s take look at why you need an RV wax. Yes, wax keeps your RV polished & shiny, but there are other more important benefits. Most importantly it offers instant protection for aluminum, paint and fiberglass.

UV Protection

An RV wax will protect your valuable investment from the harmful UV rays of the sun. If you don’t protect it, the UV rays can cause the exterior of your RV to become faded and discolored.

 Keeps Vehicle Looking Brand New

A waxed RV is a whole lot easier to keep clean, and without the hassle of washing it all the time. A single layer of wax effectively keeps road grime on the road, instead of your RV.


Aluminum Oxidation & Scratches

Have you ever wondered why aluminum can begin to look dull or have a flaky white residue?

Aluminum strongly attracts oxygen. When exposed to air it quicly makes a protective layer of aluminum oxide on its surface. This is good, as it is prevents rusting. However it looks bad.

The best solution of all is to prevent your siding from ever going through the oxidation process by covering it with a protective layer of wax.

What is RV Wax?

An RV wax is different than car waxes on the market. It’s formulated specifically for RVs, travel trailers, and boats. RV wax is typically clear coated as to not leave behind any white powder/residue, and does not contain harmful or abrasive ingredients.

Some waxes are applied in one single step. You don’t have to worry about rinsing it- simply let it dry.

While a more traditional wax will require some elbow grease, but offer the greatest protection. It will give you peace of mind that your vehicle is protected from the harmful UV rays of the sun.

When you apply wax to your RV, you can be sure that it is protected against discoloration, deterioration, and fading. You can apply it with a machine if you wish- but you can also apply it by hand, as there are no special tools required.

 

Types of RV Wax for Aluminum

Before you start shopping for the best RV wax, you need to know about the different types of wax on the market.

Waxes come in either solid and liquid form. There may also be a difference in the base ingredient such as carnauba wax or ceramic wax. Not too mention they may also contain other resins and polymers or gel coat material. The best ones will not contain ingredients that leave a greasy residue or black streaks.

Liquid Wax vs. Paste Wax

Liquid wax also known as wet wax may come in either a container or with a sprayer. For this you simply press the trigger and spray the mist on before wiping off with a pad/polisher to get the glossy finish. Liquid wax for aluminum siding provides a clear coat and protection from direct sunlight without the extra effort of polishing by hand.

However liquid wax last a short period compared to a paste wax.

Paste wax has as a solid (waxy) form, and comes in a container. This is old school wax product that still works great on aluminum. The good new is that is last for a longer period, than liquid wax. The bad news is it requires a lot more wiping.

If you only plan to use it occasionally on your RV, you might want to choose a smaller container so that it does not go bad before you use it all.

Wash and Wax

A “wash + wax” shampoo is a dual-purpose product. It both cleans and waxes at the same time. It contains a type of shampoo includes to clean the surface, while simultaneously adding a protective wax layer on the paint. Also by washing with wash and wax you eliminate the need to “wipe” and yet still get the desired results of waxing.

 

Carnauba Wax vs Ceramic wax

Carnanuba comes from the Carnanuba tree in Brazil, and is the most common wax formulation in the world. Its reliable, safe, and works on most surfaces. Carnanuba has been the gold standard for wax for a long time

That said …Ceramic Wax has been shown to be even more protective against the elements, and last even longer. There is also a significant benefit for aluminum surfaces. Most Rv’ers find that it is easier to apply to aluminum surfaces than other wax formulations. As a bonus, Ceramic wax is usually optimized for a gel coat finish.

What is the best RV wax for aluminum siding?

As you can see just about any RV wax will probably work regardless of the surface you are waxing. But some wax compounds are better than others. 

A Ceramic base is superior for aluminum. A spray on ceramic wax is easy, effective and long lasting. Our top recommendation is the Turtle wax hybrid solutions ceramic spray. However any spray on ceramic wax should be great for RV aluminum siding.
