Review on 🌞 303 UV Protectant Spray: Ultimate 32 fl. oz. UV Protection to Prevent Fading, Cracking, and Dust Build-up, Restores Color and Luster - 30313CSR by Eric Ross

I'm not sure what I'm missing here. Why is this product rated so highly? After calling the company to confirm the best product to protect our RV, this was suggested by a CS rep. I read the reviews here and also on RV review sites, so I waited until the price was "reasonable" (Revain ranges from about $7 to $24 for the same 32-ounce bottle). Upon arrival I applied some paint to a small test area on the front of our RV (both the vinyl graphic and the fiberglass panel it was glued to). It definitely beautified both materials. However, the next day we got light rain. I was disappointed when I saw the product spread across the panel. Later that night it rained again and the product was completely washed away. Who in their right mind would take that outside when the rain washed it away? While it may work for internal uses, it definitely doesn't work for external uses!
