I have recently bought this and applied it to the rear bumper guard strip on my 2015 Lexus RX350. I had washed the car a couple of days prior, so I just "cleaned" the plastic strip with a spray of window cleaner and wiped it down with a MF towel and let it dry while I walked around and got the mail, rolled the trash can down the 300' driveway and shook the bottle of stuff.
I did two coats, more or less followed the directions and I am knocked out with the results. In a little over a week, it still looks great.
Here's my impressions/opinions:
1. It's ridiculously easy to use.
2. It isn't Armor-All from the 80's.
3. It works just like advertised.
4. I expect it to last quite a while, Mequiar's doesn't seem to put out poor-performing junk.
5. I can't believe how easy it is to use.
Next up- all the other black plastic trim, including removing the front windshield cowl, which is the worst. It's the typical 5+ year old faded, gray plastic.
