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.My next vehicle I'm going to pay the initial and have a PPF or ceramic/graphene coating done right away. In an ideal world I polish yearly but if I'm honest the Traverse hasn't been polished in the 4 years I've owned it and the Pilot got polished maybe twice in 5 years since it's black. I was used Megs Ultimate Compound now I'm using the a similar Turtle Wax Hybrid Solutions product. Dual action with the light cut pads. So my process is relatively light on the paint and not really designed to remove much more than light swirl marks. But I am finding with the high quality sealants I've been using the finish just seems to hold up better for longer and the swirls aren't returning as fast.
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?"When I was a kid and we had drought conditions in the area my dad would make me help him wash cars in the rain.
