Whether you're battling saltwater or freshwater, stains or oxidation, Poli Glow’s RV kit repels water and keeps your fiberglass looking fresh for up to 6 years with proper care.
RESTORE YOUR RIG’S GLORY WITH OXIDATION-FIGHTING TECH - Boat & RV Owners! The Poli Glow Boat & RV Restoration Kit is your new secret weapon. This complete gelcoat repair kit uses a proprietary acrylic polymer formula and UV inhibitors to bring back that high-gloss finish on your favorite ride. Say goodbye to dull, faded surfaces and hello to a professional gelcoat restoration that turns heads at the marina or campground. It penetrates and seals the fiberglass for long-lasting shine & protection.
OLD BOAT? NEW TRICKS! - Poli Glow boat cleaning supplies are like a time machine for your vessel. Whether your cruiser’s still got that new-boat aroma or it's old enough to order its own drinks, this Poli Glow RV kit has the magic touch to bring back that factory shine. EACH RESTORATION KIT INCLUDES: (1) 32-ounce bottle of Poli Glow, (1) 32-ounce bottle of Poli Prep, (1) mitt applicator, and (1) white scrub pad with handle & gloves. For extreme oxidation, try the Deluxe Kit with Poli Ox!
NO MORE BUFFING ‘TIL YOUR BACK BREAKS - Forget endless boat cleaning sessions. Poli Glow's gel coat restorer for boats means less time cleaning and more time enjoying your crafts. From RVs to jet skis, if it's fiberglass, Poli Glow can make it gleam. No special tools or skills required - just follow our simple instructions (minimum of 6 coats) for a showroom-fresh look. It's so easy, you might look for excuses to apply it (but with Poli Glow's long-lasting results, you won't need to for years).
A COMPLETE FIBERGLASS KIT FOR ALL YOUR TOYS - Use the Poli Glow Restoration Kit on more than just boats & RVs. Restore your faded jet ski or refresh your sailboat for the new season. It works on both vintage fiberglass and modern finishes. Better yet, this boat wash and gel coat repair can extend the life of your fiberglass, saving money on repairs & replacements.
