Before you sit down to consider what store to visit to buy your next RV wax for fiberglass, please follow these recommendations:

Some products come with some toxic materials derived from petroleum. Consider that these can affect the environment. When you wax your RV coat, you will eventually have to remove it. A non-toxic cleaner is the best option to protect your health and the environment. The 303 (30320) UV Protectant, for instance, is a great option for nontoxic.
You want your fiberglass surfaces both to look glossy (not oily) and to be durable. Most waxes achieve this but some of them are not lasting. Two of our selections deliver a lasting shiny appearance. But all of them deliver in providing protection against the environment and solar radiation.
The price is another important factor. You probably noticed that the price range of these products is highly affordable. As with any other product, the price is usually an indication of its quality. Do not be afraid of spending an extra buck or two as this could be the difference between a great finish and a wanting one. You must consider though that some products just come at a great price.

As we have explained before, RV owners are usually looking for durability and a long-lasting protection. This is obviously because you need to protect the large investment you made in your RV. You should consider also that the protection and care of your vehicle requires a significant time investment. Naturally, owners will look for products that are easy to apply, that allow them to wax less often and in less time.
If you already have an oxide build-up, you should know that an RV wax will not completely remove it all by itself. You need to follow some steps. If you have moderate oxidation, you can get a cleaner wax both to remove the oxide and to protect. If the oxidation is past moderate, you will have to first remove it before applying the wax.
Don't let a label tell you how to apply your product. It doesn't matter if it says to wash by hand or by a machine. The truth is that when it comes to application and cleaning, there is no much of a difference. Use the method that makes you feel more comfortable. Perhaps you like the fact that a machine will get the job done faster but doing it by hand increases your chances of finding discoloring spots or oxidation stripes.

Now, before waxing your RV with the wax of your choice take the following in consideration:

Fiberglass is coated with gel coat, which is not paint.
If this is your first time waxing your RV and don't want to risk it, practice on your bathtub. Like, for real, it is essentially the same thing.
You will probably have oxidation at some point. But fiberglass oxidizes different than paint. Fiberglass and gel coat will flake. Even when your RV looks shiny, there is a high chance there is oxidation and you will not realize it until you wax it. Consider how oxidized your RV looks to decide with what frequency you will be cleaning and waxing.
