I wanted to give graphene a try since that's all the rage right now. I chose IGL because their professional line gets shining reviews (pun fully intended) I tried 303 graphene spray, and that stuff isn't worth the price of the bottle it came in. This product however is excellent. The application is straight forward, it goes on smooth without much dragging, it flashes at a comfortable rate making the risk of high spots minimal. I am doing my own comparison. I have coated my daughters 2018 Sentra with 4 different coatings 3 are ceramic and then the IGL graphene reinforced. My observations are actual real world side by side. The water beads are much tighter or more spherical, and when washing the IGL coated panels are noticeably slicker. That section also seems to be more hydrophobic as compared to the ceramic coated sections. The car has only been coated for a little over a month so longevity has yet to be tested. IGL claims 12 months, while the ceramics claim 2 years . The only negative I have for the IGL is the smell, it's VERY strong. Definitely work in a well ventilated area. I like the way the product behaves on the panels I would definitely buy again provided it actually lasts the year as claimed.
