painting my lip~

[kenshinS14sks]

ok, it looks like crap... the place i went to 4 years ago after i got into a fender bender got me a new front bumper and lip but with no tracking on the car and just daily driven...looks like the front's been sprayed with a pellet gun... no joke

so i've been searching...or "trying" to search but with not much success. i wanted to paint the lip on my s14 either the stock gray that it came in or just a white to match the car... and if that turns out good, maybe even the rest of my front bumper. so the question is

1) could someone point me towards a link with information to rattle can this at home?

2) how do i prep, sand, paint (how many coats), clear (i've read do it in some, and don't in others)... etc etc

im not looking for show quality...just that half the bumper and lip is the original plastic color and the other half is the painted color
