Are there any touch up tutorials/guides out there?

I searched this board, and yahoo and whatnot. My front bumper has a few good scratches where you can see the primer. :o I just wanna make sure I don't leave it too noticable when I do the job, and have GM factory touch up paint ready. Pics would help.

www.autopia-carcare.com has a very good guide you can download, an e-book sorta, with detailed touch-up instructions.

www.properautocare.com too has some good tutorials.
