Finally tried out my CMX on my new to me 05 Escalade. I did a quick 2 stage polish then sprayed that stuff all over. I didn't care if it got on the glass, trim, plastics, just let it do its thing.I started using Mothers CMX Ceramic coating on my vehicles. If you get any over spray on the glass, plastic headlight / taillight lenses, or flat black trim, it doesn't effect it, and wipes right off. Just for kicks I did the windshield on my Toyota with it, and found that dried, crusty, bug juice comes off MUCH easier. Same with the bumper and headlight lenses.
Who knows how long it will last but it does nothing negative to these surfaces and likely is helping them shed water.
Just not having to worry about wax getting on things it shouldn't is enough to switch to CMX.
