This was the first wax I ever used , I've been vary of using waxes but I finally gave in and decided to try this one, easy application, smelled good, easy to wipe off, if you let it sit for a while it may get harder to wipe off. I don't think I let it sit for more than a minute. I have a white car so I don't know about it hiding swirls and sratches, I can only see them under the sun. I didn't see any wax residue.
I like how the finish feels slick and smooth, almost like when I first bought the car year ago. We'll see how it holds up, I just did it yesterday.
I will use this product again, being free also helped.
