Arrives before Christmas 
Winterizing isn't the end of adventure, it's how you make sure the next one starts right. This -50°F antifreeze keeps your RV or boat's plumbing protected through the cold so your first trip starts without a hitch.
You know the drill - one quiet evening in the driveway, winterizing in a few simple steps, and peace of mind for the months ahead. This premium antifreeze protects your RV or boat's plumbing without the harsh effects of alcohol. The non-flammable, glycerin-free formula keeps seals conditioned, fittings corrosion-free, and your system safe for potable use. When spring returns, it flushes clean so you can turn the tap without a second thought.
Labels like -50°F can be confusing. That number refers to the burst point, the temperature where your lines won't burst, not the point where the fluid stays liquid. This propylene glycol-based -50°F antifreeze provides dependable protection for moderate climates but can start to slush near freezing, making it harder to drain your system. If you're storing your RV in colder regions or for an extended subzero stretch, step up to Prime Guard -100°F RV & Marine Antifreeze (PG96ZR) for reliable freeze protection.
