Meguiar's M6301 Flagship Premium Marine Wax is a solid choice for those looking to protect their RV's fiberglass surfaces. It excels in providing UV protection, which is essential for preserving the appearance and integrity of fiberglass over time.

There are a few points to consider. The product is most effective only after the surface has been cleaned and restored to a good condition, which means it might not be a one-stop solution if your fiberglass is heavily oxidized or in poor shape. Additionally, while it does provide a good level of shine and UV protection, some users may find that it requires regular reapplication to maintain that protective layer, which could be seen as a drawback for those looking for a longer-lasting solution.

The 1-gallon container is particularly beneficial for owners of larger RVs or boats who need a more cost-effective solution for extensive areas. However, the wax is available in smaller sizes for those with smaller vehicles or less frequent needs.

Users praise the ease of application, noting that it saves time by combining cleaning, polishing, and protection into one step. A notable drawback could be its performance on heavily oxidized surfaces or deeper scratches, as it is designed specifically for light defects. Additionally, while the product provides a good shine, some users might prefer a separate high-gloss finish product for an even more reflective look. Given its balance of cleaning, polishing, and protective properties, this wax is a solid choice for RV and boat owners looking for a comprehensive maintenance solution.
