Fantastic product. Non-greasy. No sling.
I have been a professional detailer for over 35 years and I have tried almost everything out there. Allow me to explain why this is my go-to tire conditioner of choice. Following the instructions, you should really clean, clean, clean your tires first. You don't want any dirt, oils, or older products left on your tire. Sometimes this means you have to clean the tire 2 or 3 times to get it completely clean. This gives you a perfect canvas for this product to work its magic. Here is a tip to make your bottle last for years: Wear a disposable glove and spray a little bit of this product on a small piece of a foam sponge. (I buy a wash sponge and cut about a 3 inch piece.) Use the sponge to apply it to your tire. This will let you work it into all the fine lines and lettering on your tires, and it doesn't waste any due to over-spraying! I recommend that you never spray this directly onto your tire, but spray it on a sponge and then work it into the tire. By pushing it into all the grooves in your tire, this tends to make it last even longer than just spraying it directly on and wiping. You can go back and do a second pass if you want. The sponge will get loaded with the product and it will require less and less as you continue. The company would probably rather you just sprayed it on directly because you will use a lot more product that way. I hope they don't get mad at me for giving away my secret that will make your bottle last way longer than expected!
When I am done with all the tires, I place the sponge into air tight storage bag for the next time. I have been using this for a few months now on a lot of vehicles and I have barely used any product--maybe a quarter of a inch's worth from the bottle. Every tire I finish looks better than a new tire without all that greasy or super slick look. There is absolutely no sling to wipe off the car panels, and the it really makes the tires "pop" when you look at them. It lasts on my tires for weeks, even after repeated car washes.
In conclusion, I'm a fan for life. I haven't seen anything else that works quite like this, and for as much use as I can get out of one bottle, it has saved me so much money already! Be sure to try the sponge application method and you will agree with me.
