Neither are waxes and both are polymer based. One is $8, the other is $13. Both got some great reviews. Have any of you used Nu Finish or the 3M? Oh, I read somewhere that I should clay bar the vehicle even though it's new. Is that good to do?

I've been using nu finish for a long time, easy to use, lasts a long time, seems like good protection.

I never tried either of those. I use the Turtle Wax Ice, which is a polymer also. It's main benefit is ease and speed of application. It doesn't last near as long as a paste wax. The clay bar is a good idea if your finish feels a little rough to the touch. I use it mainly on tar spots and baked bug guts. Works great.

Not sure on the clay bar, I use WD40 to remove bugs and tar.

The Nu-Finish seems to last a long time, and seems like good protection.

+1 on the Nufinish.
I have ued it for years (prob
ably more than 10 years) on my cars after I was rather disappointed with several waxes.
Nufinish is really-really durable. I typically use it just twice per year. The water still beads after many washes.

I know it is an old formula, it may be that there are better products by now...

Ditto bass567. I can't imagine worse conditions for a car's finish than New England. Temps can get over 90 in the summer, well below zero in the winter, and the DOT is generous with the salt and sand.

I'd go for Nu-Finish too. I have some other stuff I've yet to apply, but a friend and his brother are car enthusiasts and highly recommend Nu-Finish when I asked what to use on my wheels and Jeep. My buddy uses it on his vehicles and will use it on a opel GT he's rebuilding, his brother uses it on a brilliant Z06. Even when I took advantage of a deep discount at a car wash, the guy buffing vehicles was using it (the results in my avatar- though in the shade under trees).

Nu-Finish for me. I even used it on the windows, which seems to help keep them clean.

I've used the Nu-finish and it does give an incredible shine. When I was going back and forth between Raindance wax and Nufinish, I noticed the Raindance lasted longer but less shine. I have no complaints about NuFinish other than it did not last as long as the wax.

I'm also a longtime NuFinish user.
I haven't found abything that lasts longer.
This year I've been trying Black Magic, and it is a pain to take off because it smears. It lasts a while, but nothing like NuFinish, which I will be going back to.

I use Nu-Finish (liquid) and have excellent results - goes on/comes off easy, good shine & lasts quite a long time. Did the Pat in July and water still beads nicely (changed to snow now :mad:). Anyhow, I'd recommend Nu-Finish from years of experience using it.

For me, Nu Finish works better than 3M in terms of shine and long lasting effect.

I was a longtime NuFinish user, but swtiched to a product called Rejex with much better results and a longer lasting finish.

I use Nu Finish but have been wanting to try rejex. Thanks for the post.
