I just want to remind those with pro + applied to their vehicle. Nature always wins even if you throw a coating into that fight. Pro + will definitely stand a much better chance but if you spray your car with a garden hose it will leave spots behind with or without a coating.
To Kim with the 03 Murano, an uncoated older vehicle will not be looked at with the same criticism as a newer coated one. There may be water spots and scratches on it that you can't see. Even if it is in perfect condition is has no bearing on the other vehicle. No 2 cars are subjected to the same elements.
Water spots will form on a coating but come off like a smudge on a mirror. Dilute wheel acid to 2:1, spray liberally on a good quality microfiber let it dwell for 10 seconds then wipe with onr dampened micro and inspect. Repeat if still visible.
To crazytrucker, black vehicles are a gorgeous color when coated but you assume all potential issues when you choose that color - it shows everything whether good or bad. When dealing with an installer you don't trust or are not sure he is taking every step to help you please do not give up on having him fix the issue. He may have confused you with using a little bit or putting it on thick. None of that matters to you. It is irrelevant to the situation. What I would say to someone who took my hard earned $1,300 is, fix this issue or I will give you a 1-star review on every platform, as well as Facebook and I will call optimum to have you in question as to not addressing my issue. Send them emails as well to the same affect.
Being an opti coat installer I know whereof I speak regarding customer service. I go out of my way to make sure my customers understand everything and I will go to the ends of the earth to remedy the problem. Make him do the same with a bit of heat from you.
I hope this finds you to be useful and please let us know how everything turns out 😁😉👍
