Well, I am a person who likes high gloss, unlike others here. It fills in this role well for high gloss, since there are not many tire shines out there anymore that are truely high gloss without silicone. I have been decently impressed with the gloss of it, and it is not supposed to harm the tires.
Someone mentioned it turned his tires brown, this is a relatively new product, don't know how it alone would turn tires brown that fast. I haven't had any problems with this.
The adjustable spray has not worked well with my first can at all. It sprays in a real thin line, no matter what, and I do have low profile tires, and it is still way too thin. I think it was just the bottle I purchased though, cause I messed with it and pulled the spray cap off. I think that messed it up. Will try another one.
