ok i bought the gm touch up spray paint and the touch up lacquer that comes in the bottle with the brush....and i was wondering what preps i should to do get the spots ready for painting....and which should i use?....the spray paint or the touch up bottle?

TOUCH UP BOTTLE WITH THE BRUSH! The spray is for BIG spots! Just clean it off and apply the paint by dabbing it on this helps build up the thickness and prevents brush strokes.
