so what i would like to know is what steps do i have to take to get the desired results i am looking for?

You have to tape them off and sand and paint them..

i wasnt sure if i had to like sand all the black off or not

I have not done much with painting, but I've done a little.
You can do it either way. Concerns if you don't strip the paint off are:
- any damage or peeling to the new paint due to issues with the old paint underneath.
- despite primer, the old paint having an affect on the new paint.

I believe what you want to do, you can accomplish without stripping the old paint all the way off. The key is to sand it to where you don't have hash/score marks in the paint, that your final sand was down with a very fine grade sand paper so the surface is "scuffed". Make sure to cleanse the area of sanding dust and other impurities (I don't recall what is the best method for that, I know a tack cloth can help, but I want to say there is a chemical you can wipe with the assist). Old/fine sanding dust, oils (even from your hands) and other impurities can cause grief.

Make sure when you spray primer, paint and clear, you are in as clean an environment as possible to avoid dust blowing into your paint. When you are done, sometimes wet sanding the clear coat may be required, followed with some buffing.

Read up, take your time.

Well, I got it done last week and here's the outcome, I like it alot, now I need to do my rims

Nicely done!

Looks good man.
What kind of paint did you use?
Did you use clear coat?

Looks Nice..

i used the same type of rattle can paint from vht,3 coats of duplicolor prep spray, 4 coats of orange then 5 coats of clear gloss

As you heard me say before I think a matching pin stripe. I have never painted a pin stripe but there is also pin striping tape or perhaps you can find a local guy who could paint it.

No matter what, nice custom work!!
