3-IN-ONE RVcare Rubber Seal Conditioner with UV Shield helps ensure optimal seal performance and extend the life of rubber seals on slide-outs, windows, doors, and compartments. Its long-lasting UV-protection and water-resistant silicone formula works in extreme temperatures and weather, helping you to actively prevent cracking and fading, and ultimately extend the life of your rubber seals. The two-way Smart Straw makes it easy to apply this rubber seal conditioner in either a narrow stream for precision, or a wide spray to cover large areas faster—and without any overspray or messy residue. Hassle-free RV travel has never been so easy.
