If you're only going to apply it when you wash the car which I presume is once a week like most people? Then something just like a quick detailer, Hybrid V7 or Finishkare 425 are good might be a option.
But as stated, this will only seal in stuff that other products are used for to remove. Such as tar, iron, dirt embedded in the paint, swirls.
Thats why people go to more extensive lengths and apply waxes rather than QDs to help seal the paintwork for longer maintaining its finish as best possible.
theres all in one (AIO) polishes which also offer a bit of protection, Autofinesse Tripple is a good product, but is that what you're after? It's still a polish type product which you need to manually work in by hand to get gains where the QD is just a spray on wipe off.
