That post will run dozens of pages, although many have written books on detailing if you’re so inclined. YouTube is also a great resource.
The single most important thing to ensure long term performance with any coating is to eliminate the daily cleaner, he will inflict deep damage and will not only scratch the coating but over time will do irreversible damage to the paint.
Good coatings from any of the top tier brands don’t really require much maintenance. Unless you do something to the paint outside normal conditions, like sand it, take rubbing compound to it, repaint a panel, scratch it by improper washing or let very corrosive elements buildup on it (like bird poo).
Special mention of bird poo, most people don’t know how corrosive it actually is, if you see any, remove it asap. Anything over 8 hours even on coated paint will stain, with 48hrs and above doing permanent damage, a week and it’ll probably eat through your entire paint system and no car mfg./coating mfg. will warranty it, as it’s user negligence.
As for decontamination, it may or may not be needed depending on driving and parking conditions. Worst case, you’ll need mineral remover for hard water spots, tar remover for tar spots and ferrous remover for rust spots, that’s it. You likely won’t need all three, just mentioned for your knowledge.
In case you do need any of the above for decontamination, your coating won’t need reapplication as they are safe over coated paint. Do not clay or use abrasives for decon as that will swirl the paint and require polishing and reapplication.
For maintenance, you can use just air or water + air in between foam
washes. I’ve sent links to short clips I made earlier in this thread showing the above. If you can’t find them I’ll link again.

A microfibre should not be a part of your washing and drying routine after a high quality coating has been applied. You need to rinse with a pressure washer and dry with a leaf blower most days, with a rinse-foam-mitts-rinse-dry every few days/weeks (contact wash). Max you’ll need is glass towels and a plush 550gsm or higher towel to catch drips (dab, don’t wipe.)
During a contact wash use multiple mitts and after both sides are done, go to a fresh mitt. You’ll need 7-8 mitts and will eliminate the second bucket, also much safer than the 2 bucket method where a single mitt is reused. Cross contamination between panels is effectively eliminated as well. Work top to bottom, do not use your paint and glass mitts on wheels or silencer tips.
Have a dedicated wheel mitt/towel instead. Ideally one mitt for the wheel face and an older towel for the wheel well along with a long handle brush to get the brake dust.
Paint is butter soft (even after coating), the golden rule is to never touch it without adequate lubrication. Water is not a good lubricant, it’s a solvent, that’s why we use foam shampoos (it’s not for cleaning, it’s for lubrication). It ensures your mitts glide over the surface instead of digging into it and scuffing it.
Never do waterless washing as it’s a sure shot way to destroy your paint over time. Rinseless washing is safer, provided you do it correctly (most folks don’t). As the name suggests, you don’t need a final rinse with a good rinseless wash like opti no rinse (ONR) but you still need a pressure washer to get all the dust off before spraying and wiping.
At this point, there is little difference in effort between a foam cannon and rinseless, either will work provided you use multiple mitts/towels and keep switching to a fresh one after all sides are done.
Jopasu duster is another way to damage your paint and coating, dry abrasion never works out well and after a few attempts you’ll see the swirls on a sunny day. Instead use a powerful leaf blower to remove loose dust in a touchless manner, like an air duster. If you have a covered garage, compressed air also works great.
Did the installer tell you what brand of kit was used? Good brands don’t require much maintenance, near zero in fact provided you don’t abuse it by washing incorrectly. Mineral remover, tar remover and ferrous remover are need based and may not be needed in certain cases.
Now that it is swirled, you need to have the paint corrected again and re apply the coating. Note that paint on new cars is wafer thin and constant polishing will lead to premature clearcoat failure, do check with the shop on how much they’re removing exactly. You should get a clear range like 3-4 microns. If they appear confused or are not clear or don’t have even a basic DFT gauge, find a better shop.
Will also suggest sticking to authorised installers of any of the major brands in the pro coating space. It’s not a guarantee of quality but a big step in the right direction.

This isn’t true, swirls aren’t actually circular scratches, they are straight lines when viewed under a microscope.
Wiping in circles is no better or worse than straight lines. If you’re going to scratch, wiping in straight lines will scratch just as easily.
