I am looking for an advice on how to properly paint a front splitter that I bought on line but the paint job that they did is not the best, because after 3 days of street/hwy driving there are quite a few rock chips. So, I think I will be repainting it myself.

Thanks

 

3 days of driving will give u rock chips. it happens doesn't mean its a bad paint job

the best way is to either have a professional do it or have a professional spray booth and spray the paint on (not spray paint rattle can)

thats if ur painting the whole thing

if u just need touch ups...if its small, touch up paint is enough (it usually comes with a small brush)
if its fairly big size...u can use the same touch up paint, but spray it on with an airbrush so its more even/blends in
