I'm happy with it.
I bought a Finish First kit for my Durango a couple years ago, and also used it on my '65 Dodge Coronet convertible. First you wash, then you apply the cream. Let it haze and wipe it off. Not much effort needed. The cloth will turn paint color, so it is taking a bit of the paint off, but after that it is an incredibly smooth surface. I really havent' had to wash my convertble for a couple years. Really. Just keep it inside and use a California duster. The Durango lived outdoors, and the FF could probably have been applied a couple times, but I never bothered. Now I have the Ram, so I'll probably try it in a couple months. My guess is that there are other quality products out there, but I happened to buy the Finish First stuff. Hope this helps.
