Get incredible shine and protection with minimal effort!

Max's RV Hydro Pearl SiO2 Coating is the ideal way to coat your RV with glossy protection that lasts month after month. This innovative formula features the ultra-easy spray-on, rinse-off simplicity you need when coating a large RV. Max's RV Hydro Pearl SiO2 Coating simplifies your maintenance routine without compromising on the level of protection, gloss, or water beading you'll achieve!


  • Adds extreme gloss
  • Coats surface with durable, lasting ceramic protection
  • Spray and rinse formula
  • "Wax" your RV in a fraction of the time
  • Self-cleaning effect keeps surfaces cleaner between washes

When you've got an RV you want to be using it not fussing with maintenance! The size of most RVs is enough to drive some people to ignore waxing or sealing completely. So what's an RV owner to do when they want protection and gloss, but don't want to take time out of their vacation to do it? Coat it with Max's RV Hydro Pearl SiO2 Coating of course!

Max's 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 RV and still have time to enjoy it! You'll also love the fact that Max's 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!


  1. Shake well. Ensure surface is cool to the touch.
  2. Apply AFTER you wash your boat or RV, while the surface is still wet.
  3. Working on an area no larger than 10’ x 10’, spray Hydro Pearl directly onto the surface.
  4. IMMEDIATELY rinse off using a strong jet of water.

Note:  Apply to all hard, smooth surfaces (paint, gel coat, glass, metal). Do not use on underfoot surfaces.

    Pearl SIO2 coating

    Very good product and holds up really well. I just wish it was made to spray on after washing and either left on the surface or rinsed off without the need to come back and dry the entire RV. If it's a dark colored RV it has to be dried off by hand or else it may leave splotchy areas/spots from it bonding to the paint.

    I like the marine and rv coating. It applies easy and seals the exterior. I don't get a slime line from being in the water and dries off easy too! It works especially well under my T-top where it's difficult to apply normal wax.

    Excellent Product

    I was surprised at the effectiveness of this product. it will be a massive time saver for the customer. The customer will be adding this to their wash routine in an effort to save time and labor hand waxing. Truly is a watch before your own eyes as the coach became hydrophobic immediately as it was applied, almost Voo Doo like lol. Showed customer once how to do it, they then immediately purchased a gallon. Typical Mckee's experience, quality products every time.

    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 McKee's I ordered a bottle of McKee's 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 didn't 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 can't speak to the durability but if this holds up I'll 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. I've used mutli-coat, high end polishes on my cars for years. After applying this to my RV I'm going to order up some McKee's Hydro Blue Sio2 and see how it works on my truck.
