I just to get everyones opinion on spray on detailers. Such as black magic or something of that nature, the inbetween wax sprays. Every time i use it you can always see streaking and marks when it is in the sun. I was wondering on how to avoid any of this. Thanks guys
Yeah the black is really hard to maintain. I don't use the spray, I just use meguires 3 step (cleaner, polish, wax) that is the best way I have found but there might be other ways too.
