SiO2 Leather Guard

The twice a year leather protectant!

McKee's 37 SiO2 Leather Guard is the ultimate protectant for leather trim. This high-tech coating blankets your vehicle's leather upholstery in a durable shell of protection that resists abrasion. Powerful UV50 light absorbers prevent fading, cracking, and long-term discoloration. SiO2 Leather Guard only needs to be applied twice a year, making it a fantastic choice for a daily driver. Use on leather seats, door trim, arm rests, dashboards, and hard smooth surfaces. Imparts a clean, OEM-matte finish that feels smooth to the touch. Prevents dye-transfer from blue jeans, and also protects against damage caused by sunscreen. Works equally well on leather handbags, leather shoes, and leather furniture.  

Benefits of McKee's 37 SiO2 Leather Guard:

  • High-Tech sealant for leather surfaces
  • Perfect for smooth and perforated leather
  • Prevents dye-transfer on lighter colored leather
  • Protects against UV rays
  • Resists wear and tear caused by abrasion (getting in and out of vehicle)
  • Best defense against sun screen
  • Protects delicate leather stitching
  • Hyper-Concentrated - one bottle, applied twice a year, will last over 10 years
  • Can be applied to vinyl and rubber surfaces as well!
  • Infused with SiO2 for long lasting protection

  • McKee's 37 SiO2 Leather Guard is not a leather conditioner - it's a high-tech coating that not only outlasts a traditional leather conditioner or protectant, it provides superior protection as well. SiO2 Leather Guard blankets leather upholstery with a crystal clear, durable shell of ceramic protection that protects against dye transfer from blue jeans, abrasion, food spills, suntan lotion, grease, and oily grime. Dirty leather will wipe clean using a dampened microfiber towel.  SiO2 Leather Guard is formulated and approved for VEGAN leather as well.

    Leather upholstery is the single most expensive option in most new vehicles. What costs you thousands of dollars is often neglected during ownership of the vehicle. Applying McKee's 37 SiO2 Leather Guard twice a year is a low-cost investment to keep your vehicle's leather upholstery looking and feeling new for the life of the vehicle.

    Thoroughly clean leather using McKee's 37 Leather Shampoo 70/30. Apply SiO2 Leather Guard directly onto a foam applicator pad. Work SiO2 Leather Guard into the surface using a circular, overlapping motion. Apply more as needed. Remove excess by gently buffing with a clean, dry microfiber towel. Do not apply to suede.

      McKee’s 37 SiO2 Leather Guard

      Used this on my 98 Mitsubishi Eclipse GST front leather seats. Works well on plastic vinyl such as your interior door panels, dash board, rear quarter panels, pillar trim, floor consoles and anything plastic. In the photos and video upload I have here a floor console I’m restoring to like new condition for a 07-08 Hyundai Tiburon GT and SE trim 5spd or 6spd manual transmission. The McKee’s 37 SiO2 Ceramic Leather Guard used on this brought the color to its full richness. It doesn’t make it too glossy or too dull just the right OEM sheen that you expect when you first buy these cars new off the dealer ship lot. I will stick to McKee’s 37 as my go to detailing products whether it’s for exterior or interior purposes.

      Repeat Purchase

      This product does a great job, easy to use, and goes a long way. Just needed another bottle after using it on all our cars and even a friend's Mercedes GLS.

      Excellent, just follow directions. It deepens the color and you can feel the protection.

      Mckees37 SiO2 Ceramic Series Leather Guard.

      Ease of use is good. Haven't really had an extended chance to see endurance since I received this product days ago but from my understanding this is an upgrade to Mckees37 original leather guard SiO2 Leather Guard Review

      Great product

      The leather utv guard leaves leather seats with a nice semi shine. They are easy to clean after treated.
