All over my truck I have nicks and marks. The truck is Oxford white ford according to my dad. (missing door sticker)

How can I go about painting them deep marks and stuff. Like brand of paint/ do I have to go over it with a clearcoat?
My front fender also is yellow now because of missing clearcoat so I assume I have to take that to a real shop to get completely redone.

Basically any tips to a novice painter are awesome!

 

Just stray away from those touch up paint pens if you come across them.. The paint put into a scratch or dig is raised when it dries. Can't tell far away but enough for myself to notice a few I did

 

I got a bunch of marks. A pen is one of the things that pep boys had. Ill try that on the smallest one because I don't want it rised like you said.
