Re: touch up paint
IF you are anal about the stone chip, dont bother touching up....
Why... because the touch up will be a blur matt "chip" on your bonnet after a while. There is no clear coat on it to make it shine, and even if you can find a way to do that, its gonna be a pimple size bump on your metal.
Its gonna be almost impossible to blend/match with the current body work. Either leave it alone, or if too big a chip just go spray. And please dont do what "localized" spray, its bs...
Gd luck....
