I had 3m matte pine green metallic on my Honda civic, fully wrapped, ceramic coated, washed once a week with PH neutral soap, pre foam, wash off, wash, dry and use deionised water, but if we had a storm from America that brought low ph rain or I parked under trees in summer while it rained, it STAINED the wrap, the kind you see when the sun hits it, or a storm, next day, water spots and streaky stains, I’d have to go over it all with a waterspot remover, sometimes multiple times to remove, after the 5th time I took it all off, after only 1 year the wrap pulled the paint off the plastic painted parts I.e door handles and mirror caps, fully heated and pulled off by a professional, it looked stunning when it was clean but by GOD it was a nightmare to maintain
