I live in Iowa and need to purchase a wax to use on my Mustang. Which one would you recommend that I use in 45-50 degree weather?

 

Really it is your personal preference. As long as you don't go below those temperatures you will be alright. I would use a spray wax for winter. That way you can spray it on and wipe it off real easy. I carry Optimum Spray Wax that lasts as long as most carnuba paste waxes. It is also currently on sale and comes with a free microfiber towel.

 

Put it inside while waxing it and hands down the best wax ive ever used is the NXT wax i use the liquid it works so well ... i also use wax as u dry when detailing .

 

I agree. I`ve used both the liquid and paste. They are both real good. I do prefer the paste though. I seem to get better coverage with the paste.

 

Even though I'm living in Southern California where it was 80 last week, I do empathize with 40-50 degree weather... it's likely a tad cold cold for any wax to work, though it certainly should vary by formula.

Some of the guys over at waxforum.com are recommending that ideally you're working at 55-60 degrees, so if you can get in a garage and safely use a space heater to warm things up a tad, you'll likely be a bit better off.

It won't hurt to try a section at 40-50, but it may be a bit of an experiment, and will certainly vary depending on humidity levels.

And you're probably going to want to wash as well. On cold winter days here (about 65), I use a warm water blend in the bucket, and if it's really cold, I'll hook the hose up to my garage sink and run warm water out of the faucet. (You can get a threaded adapter at a hardware store.)

As for wax, I'd probably look at a one-step carnauba cleaner wax like the Mothers since they've got pretty good polishes in that which should work good in any weather. I haven't personally used NXT, but I hear a lot of guys who like over-the-counter synthetics have been switching to Mothers FX or another brand because NXT's durability seems to be short-lived, and inclement weather just makes that life much shorter.

Juztang's advice should be good as he's in cold weather country, and a spray wax sounds like a really good idea... get the job done quickly and do it as often as you can. After the winter is over, then do the full treatment to restore the finish.

A lot of your approach is a personal choice... there are a lot of products out there, but frankly you're probably going to have to experiment with a variety of them when you're talking inclement weather.

Good luck!
