This innovative formula features the ultra-easy spray-on, rinse-off simplicity you need when coating a large RV or boat.

When you’ve got a boat or RV you want to be using it not fussing with maintenance! The size of most RVs and boats is enough to drive some people to ignore waxing or sealing completely.

Coat it with McKee’s 37 Marine & RV Hydro Pearl Sio2 Coating of course!

McKee’s 37 Marine & RV Hydro Pearl Sio2 Coating creates incredible gloss and unmatched water beading with minimal effort. It truly is as simple as spraying onto the surface and rinsing it away with a strong jet of water. You can “wax” your boat or RV and still have time to enjoy it! You’ll also love the fact that McKee’s 37 Marine & RV Hydro Pearl Sio2 Coating keeps surfaces cleaner between washes thanks to its extreme hydrophobic properties — a quick rinse will remove most dirt and grime!

I would recommend to a friend
RV Hydro Pearl Sio2 on my 5th wheel I washed my 39 5th wheel last week. I was in no mood to hand apply sealant after an 8-hour washing. After some research and a chat with Nick at McKees I ordered a bottle of McKees 37 Marine & RV Hydro Pearl Sio2 Coating. My wife and I rinsed down the 5th wheel one 8 section at a time, sprayed on the Hydro pearl and re-rinsed the area. The entire 5th wheel took us about 35-40 minutes. We used a leaf blower to dry it off and could see no spotting. Even on the windows we spot free. It happened to rain last night, and I didnt see any spotting this morning either. The water runs off as well as any hand applied polish ever has and the shine is as good too. I cant speak to the durability but if this holds up Ill never apply anything else. The product worked great and was simple to apply. It saved me 4 to 5 hours of hand work. Nick told me to use 8 sweeping pumps per section. This was the most difficult part. I just felt like I had to apply more product.
Ive used mutli-coat, high end polishes on my cars for years. After applying this to my RV Im going to order up some McKees Hydro Blue Sio2 and see how it works on my truck.
Pros:Easy to apply
Sheds water
Seems to eliminate spotting
Customer service was excellent
Cons:None at this time
Will have to see how it hold up.
