Yes because automotive paint now is water based and not solvant based they are pretty fragile and people don't know that but a good fact for ya ... 75% of the population doesn't wash their vehicle regularly or even at all and it baffles me .. you spend how much money 💰 on a vehicle .. if you do oil changes and things like that why wouldn't you do the same which is part of maintenance and wash the damb thing .. all my vehicles iv had now keep on mind I have professional automotive detailing experience and so all my vehicles I have never had an issue with swerl Marks as I'm OCD with the paint work as I know how fragile it really is and so always washed it how I was taught in my certificate auto detailer course with two bucket wash and a very high quality car shampoo that has allot of lubricity as the shampoo is so very important as it's not only your decontaminate but it's a lubricant to not in stall swirls and maring into the paint that requires hours of work to correct depending on how bad it is . The way my CX 30 looks now and believe it or not is going on 8 months old .. it's will still look this good in 3 years after the lease is up and what I'm trying to say is I wish more people wher like me and took this much care of their vehicle and just do the required maintenance and correct washing but so many people just thick ah automatic car wash that's good enough... Hello scratch and fade city .. do not use those stupid things .. yah summer I wash mine at home and in the winter I fill both my buckets up .. drive to the self wash and all I use there is their pressure washer nothing else and it's really not that hard but so many people pick up that horrible brush and you might as well get out a strip of sand paper and throw Dish soap on it and totally mess up the paint work lol 😂 also there was nothing wrong with my ceramic coating as it was hydrophobic like crazy but I know that a second coat will just add that extra layer of protection as it makes the clear coat allot harder up to 50% actually and so I wanted to get the maximum protection for the long run with my routine once a week washing.
on previous cars - and on this car even though i had dealer ceramic done, ive removed it and added zaino...
im just OCD with car washing and detailing, i'm no pro but a weekend warrior
my regular /weekly wash method is-
snow foam
rinse
2 bucket wash
rinse
blow dry
top up with a spritz
every 4 weeks add 1oz of zaino z6/z8
pre winter i add a zaino z2/z5 polish in the mix just to add a bit more protection..
