if my car is silver, what type of paint do i use. normal silver or color matched paint like touch up paint

As a fellow Galaxy Silver Metallic GP owner I am going to tell you right now that you must use Galaxy Silver Metallic WA519F, and unless you have whatever you are painting computer matched and blended it will never look right(someone replaced my drivers side fender on my car and it doesn't have the same luster as the rest of the car, it even looks grey from certain angles). As far as what kind of paint don't use those touch up paint pens they never look right, I would try some Duplicolor from a parts store. If you have access to a paint gun automotive paint would probably be best bet.
