I have a black 2015 Honda accord that I park outside, it rains a lot in the pacific northwest and am wondering what I should do to keep the paint looking good. I had a paint sealer called diamond kote applied to the car to keep the black paint from fading in the hot sun, I wash the car regularly and apply meguiars ultimate quik detailer about once a month after a wash and it keeps the car nice and shiny.I feel that I need a longer term solution like a wax or polish and don't know if I need to use a synthetic or carnuba wax or anything else and in what order I should be using them. I would like to stick to meguiars or mothers products as they are readily available here, also as far as wax goes I like to use a paste. Your help woul be gratly appreciated.
