Those vinyl headlight lids make it looks meannn lol
Actually they are fiberglass but yeah I agree, it makes it look mean!
You can wax any paint, glass, metal, hard plastic (ie head/taillights).
As for signs of protection, I go by how easy the paint is to clean, how slick it is, and how water beads up. My paint is swirl-free so I don't really go by looks, because swirl-free paint always looks good.
The sheeting in the pictures does not look uniform and I would probably say that there is minimal protection left, if any. I'd definitely be applying a fresh coat of wax.
Thanks for following up Matt and believe me, there will be more product added! My Pinnacle SSII should arrive today so that will go on this weekend for another round of testing. I also plan to take the PC XP out of the box and try it out on my wife's black Cobalt for the first time!

If all is well, it will receive a full correction followed with Wolfgang DGPS 3.0 and Fuzion. If not, then hopefully I will pick up a few tips at Detail Fest or just pay someone there to fix it!
Clutch34, in the first post when looking at the paint you really don't see the water because it's just laying there with no beading or sheeting taking place. In the second post if you look at the paint you will see the water sheeting. If you're not sure what you're looking for, the dark areas that look blotchy is actually water and the lighter areas are where the paint is dry. For the windows, I would prefer something that has a sheeting effect over beading. Now that I have opened up to other products, I'm sure I will find what I'm looking for!
CieraCL, in my personal opinion, I don't think the Meg's Gold Class is a winter wax. I'm sure there are ways to enhance the protection but that's not what I wanted to test. My goal was to test the durability of the wax alone with no QD's, QW's, or sealants.
Jenn1270, you should try testing the two products without the Collinite first and then strip down the finish and layer them. What I mean by this is strip away old wax and apply Max Wax on one side and the Meg's on the other side, run your test, then strip away the products again and apply the Collinite followed by the two products. This will allow you to test standalone products then enhanced products.
