I've been using this for about 2 years and it's my favorite gun lube.
I live in Oregon and shoot both in the summer and in the winter, rain or shine. I have had zero problems with rust after switching to AS 18, which is even more impressive as I frequently shoot corrosive ammo.
It's a pretty thin oil but works well on every weapon I've tried it out on. Not rated as a cleaner but AS 18 actually does a decent job of carbon removal too.
All this for less than 1/2 the price of CLP.
