Well after having used Eagle 1 NanoWax Spray about 2-3 times I feel I should express my thoughs and feelings on it. Sorry no pictures, price breakdowns, etc. like some other members, just a couple of my thoughs. Please take this "mini review" with a grain of salt, as with everything YMMV
I picked this up while getting some car parts for my car a month or two ago at Autozone. I read a couple positive reviews on it here, and figured why not for a little over $6 with tax. This was my first use of any type of "spray wax" on my car. I knew I wasn't going to get great durability, but figured if this can save me time and conceal swirls (black Honda :hairpull ), it would be worth it. I don't have the time or patience to spend too much time detailing my car as often as I should.
The smell is pleasing to me (vanillaroma), but I can see it being bothersome to others. Application was pretty easy. I gave it a shake before using, lightly sprayed on, wiped it around with one MF, then removed with another MF. As for time saving, I really didn't see any compared to any other LSP. I did experience problems with it streaking on my black paint. My car was cool to the touch and was in the shade. I found I had to rewipe areas multiple times to get rid of them.
Appearance wise it looked good. It did give me a nice shine, and it did seem to hide some swirls somewhat. My car is black and hasn't been polished since the fall. Once I got it in direct sunlight the swirls weren't too too bad.
Durability was medicore. I wouldn't push it more than 2-3 weeks, which I expected for a spray wax that cost $6.
Overall I feel it's not a terrible product; but there are much better choices. Not to badmouth this particular product; but I'm not overly impressed with spray waxes as a whole. They really don't save me too much time, and aren't too cost effective for a weekend warrior like me. The streaking I got with my car also annoyed me because I had to rewipe areas that I already did, which could have induced more marring, and wasted more of my time.
I think I'm going to reserve this product for my door jambs. It wasn't too durable or too time efficient for me to choose it over any of my other dedicated LSPs.
