Nanotech Surface Solutions Leather Shield - Leather Conditioner & Sealer - SiO2 & Wax Blend for Use on Car Interiors, Leather Apparel, Shoes, Boots, Bags, Furniture & More - 8 Oz.

I used this product on both my leather car seats and my couch and it's done a great job protecting them. I have used other leather products and they only work as conditioners but this one works as a sealer as well. The application process was easy and I liked that it doesn’t really smell. Very little product goes a long way.

A good product but not sure yet how well it works

- Too costly (4x/oz vs alternatives).- Difficult application (streaks, have to buff, long cure time).- Sticky when dry.- SiO2 is an eye irritant, which can damage the cornea.+ Smells decent (no crazy fragrance).It looks OK once it sets in. There are little sparkly bits like glitter from the silicon dioxide... Basically ground up quartz crystal. If you wait a bit for it to dry, and then lightly brush it with a microfiber towel, it looks even and consistent. If you let it set up without buffing, you will get hand prints and random unevenness. Normal auto leather conditioners do not do this. My main issue, is that after it cures for 24h, it still feels sticky and gross. I did proper prep, completely removing prior coatings and wax from my leather with a good cleaner. Quite bad for steering wheels. Not ideal for seats either, as it doesn't reduce friction which protects the seats. I'm going to stick with Chemical Brothers or Maguires.I don't think this is a good value. It takes about 3 to 4 oz to do two light mists on front and back row leather car seats. That is nearly half the bottle.Most smooth leather has a urethane top coat, so this won't penetrate. It is just topical. You can get urethane sealers (matte or glossy) to properly reseal your leather, which adds back a protective clear coat. This is not that.

I used this to clean up the rear seats of my Tesla after a sticky drink was spilled and dried it removed all. I used it on the steering wheel and the amount of dirt it removed was amazing and no residue left behind
