Nu Finish Liquid Car Polish

Though some car enthusiasts enjoy rubbing down their cars every few months, many consumers want car paint protection that lasts a longer time. Auto experts and consumers alike say overall that Nu Finish Car Polish is one of the longest-lasting paint protectors available.

Available in both paste and liquid form, this report focuses on the slightly higher-rated Nu Finish Liquid Car Polish. According to one organization, the Nu Finish Paste cleans better, is more compatible with plastic and lasts longer than Nu Finish Liquid, but the liquid is easier to wipe off. Consumers on Amazon.com rate the liquid higher than the paste, at around 4.5 stars (out of 5 stars) overall versus 3.5; user comments say Nu Finish Paste is harder to remove and doesn't leave the paint as shiny as Nu Finish Liquid.

In one comparison test, Nu Finish was the most durable liquid wax evaluated. User results are mixed, though. "When I reapplied it after 30 days as instructed, it lasted close to a year," says one user at Amazon.com. Another writes, "I have never been able to get it to last a year, but it definitely lasts for 3 to 6 months MINIMUM," summing up the majority of consumer comments from Amazon.com and AdvanceeAutoParts.com. In comparison, most car waxes don't last longer than three months.

Consumer reviews say that with Nu Finish, you trade visual enhancement for longevity. "It may not produce the best shine I have ever seen but it provides protection and beads up on a car's finish for a long, long time after application," says one Amazon.com user; while another remarks, "Doesn't penetrate as deeply as paste wax." Another reports, "To me, the shine is just as good as a carnauba wax and should hold up much longer. Even if it lasts only half a year, that's much longer than what carnauba can do."

Though most say that it is very easy to wipe on and off, some users warn that it can leave a white powder behind after buffing (on Epinions.com one owner says that you "need an old toothbrush to brush away dried white paste out of cracks"). "You should be extra careful around plastic when using this product." writes an Amazon.com user; many consumers remark that Nu Finish permanently stains trim and rubber. 

According to Darren Priest, a professional car detailer, Nu Finish is actually a sealant, not a polish. Nu Finish doesn't contain any polish abrasives that can restore color or remove oxidation, and many Amazon.com users note that it doesn't remove water spots or scratches, either.
