Nu-Finish is a mixed bag like all products. It was designed to be many things to many people by doing many things well even if not great! Meaning, easy to apply/remove, remove oxidation, long lasting shine, affordable etc. I have seen many wax products do what Critic mentioned, at one time or another. Sometime it happens if the product is applied too heavely/thick or maybe the N-F is old(sitting on the shelf too long) even if just purchaced.
I have used N-F in the direct sunlight and it dries nicely and removes easily. The only thing I didn't like about was how much dust residue it left behind. I always felt like I had to redust my vehicles after waxing with N-F. Other than that, I thought it was a fine product. Also, it was one of the easier products to remove from black trim if gotten right away as demarpaint would disagree(we each have our own experiences) and I don't doubt that this has happened to others. I don't think that N-F is a perfect product nor for everybody. You need to find the product that works best for you. I have seen N-F not work well on certain paints such as vehicles that have been repainted or certain pannels repainted. Years ago my dad had an LTD that had the front fender and door repainted and any wax I used on his car was hard to remove on those two pannels but the rest of the car was fine.

I have used products such as YELLOW WAX that hides scratches and makes the paint really shinny, almost wet...until the next washing! I first thought this stuff was the Cat's PJ's but, not so. I still use it if I want the paint to look good for a week.
