However, it's worth noting that the product isn't water-resistant, which may limit its use in environments where water exposure is a concern.

Evercoat Rage Gold Body Filler stands out as a versatile option for automotive body repairs and is particularly well-suited for those looking to work with fiberglass, aluminum, and galvanized steel.

However, there are a couple of drawbacks to consider. While the filler has impressive adhesion, some users may find that it is slightly heavier than other options, which could be a concern for those seeking a lighter product for minor repairs. Additionally, as it is a one-gallon size, it may not be the best fit for individuals who only need to perform small touch-ups, leading to potential waste if not used up quickly.
