Looking for some opinions of products to use on my car for winter prep. The paint is Mazda's Lapis Blue Metallic. I currently have a few coats of Natty's on the car, but am battling the elements and all the dust and debris in the air. I plan on doing AIO/SG(x2-3) but am looking for some opinions on this combo on my color and any suggestions otherwise. I want something that will be durable enough for the realtively mild winter in Nashville, but I also want the paint to look its best.
Here's a pic of the car with Natty's (Regular Paste):
Any input is appreciated.
