I've been using the Turtle Wax Hybrid Solutions Ceramic. I use the Porter Cable DA to apply with an orange foam pad. I just did my son's car with him yesterday. I haven't done real polishing/paint correction in a long time unless there are some that really stand out. The layers of polymer products definitely help. I'm using some Adams Graphene spray as a coat in between. Just not enough time and energy to really put into it. That and the constant abuse of roads and parking lots. I try not sweat the petty things or pet the sweaty things now. My Accord has a bunch of little dings by quarter panel from a car door in a garage from previous owner. I see them, nobody else really does unless I point them out.
I do try to give all the cars a quick clay mitt and a fresh coat of wax before winter. Helps the snow/ice come off easier and protect.
Yesterday on my son's car we did the windows with Ceriglass and glass polish pad. His windows were bad with water stains from sprinklers etc. Huge difference and not hard with the DA. Also rounded off many of the chips on his windshield. They are still there but a lot less glare. 2010 Forte with 168K. Unless it gets a lot worse it won't get changed unless it cracks. I'll polish a couple more times if needed.
One of my favorite coatings was Ultima Paint Guard Plus, wipe on and walk away but no cleaning/polish. I ran out and haven't bought new because I have so many other waxes/cleaners/coatings. Some I have not even tried yet like the CarPro Hydro 2. Squirt bottle on, high pressure stream from hose to activate.
I've done that with the kids, they thought it was kind of funny. Also went swimming when it was hot and raining. "dad it's raining" "are you afraid you will get wet?"
