I used to go totally crazy and have many of the tools, pads, polishes. I'm pretty good with doing the paint corrections if I have time and energy (and my knee is not in pain). The professional ceramic coatings are excellent but do cost a lot.
My garage is like Donald's. Too much other crap and no room for a car currently. Between kids, FIL, wife there are 6 cars so all outside and all DD. Acorns, leaves, road debris, stupid people in parking lots etc. I try to keep them all clean and protected. They do get a clay bar/mitt treatment probably 2x per year. I'll polish out if I see issues but mostly now use the Turtle Wax Hybrid solutions Ceramic wax. In between at washes it might get a spray coat of Adams Graphene. Wax type sealers all applied with an old Porter Cable DA and various pads. I'm not hand waxing anymore and haven't for a long time.
I used to use (and sometimes still do) Klasse All in One that also works well. One of my older favorites as long as car was clayed and decent prep was Ultima Paint Guard Plus. Wipe on a thin layer in no time, walk away, no polish or buff. I had multiple cars that looked great after many years (except that road rash on front). It was so easy that you could apply a coat in 5 minutes after washing normal. Kept it nice and fresh. The Graphenes etc now do that also but need the buff.
My biggest thing now is a good easy coat especially before winter so snow/ice clears easier. Looks good from ??? feet away and driving by. Protected from bird crap and other fall out like tree sap. They all have dings and scuffs on some from others, rock chips from highway, micro marring from car wash convenience. They are clean, water beads, glass coat water repellent is good. OCI's are maintained
Some day maybe I can have a nice show car type, garaged vehicle. Too many other things in life to worry about and plan for in the meantime. We all have our priorities and habits. Even after you spend $500-1000 on the coating it still needs washing and top coats to maintain from what I know of.
Another QUICK coat if you need something is the CarPro Hydro2 Lite. Wash the car, spray this lightly, hit it with the hose on pressure, dry it. Real slick for at least a couple weeks. Great as a quick topper before a storm if possible. I had tried it on the Tucson first. Standing on a work platform rested my hand on roof for drying and almost fell off as my hand just slid off.
