I'm sorry, but any ad that won't tell you the price raises a red flag in my opinion. Probably very expensive. Believe me, if it was that great the car geeks would know about it and be using it. True car nuts manage to find every good product no matter how obscure. There's a lot more to protecting your finish than a product lasting a long time. What about clarity, gloss, slickness, depth? Don't believe the hype and try the stuff that the people here have actually used and can post an intelligent review on as opposed to what the seller tells you. I would try the Platinum products sold right here. Great deep gloss, easy to use and good longevity too. Buy the kit with the applicators and the spritz finishing spray. Great products and a great deal too. enjoy.
