How to sand/prep/paint ABS plastic., Need help Options

[ILoveMySilly97]

Some of you may know that I was going to get a paint job but due to me purchasing a new set of Enkei RPF1. The new paint job is put on hold til summer maybe. I decided to just repaint the GT4 rear splitters that I have myself. Since it doesn't look too hard to attempt. I never done any kind of sanding or painting or yea. Just a FYI I sucked at art. LOL! But to get to the point. I need help to repaint them. As of right now they are RED and want to repaint them with Silver 119. They are OEM and not replicas.

My questions:

What grade sand paper? Wet or dry sand?
What's the best primer for ABS plastic?
Need help on this DIY repaint.

Specs:

GT4 Rear Splitters
OEM ABS plastic material
Currently still have the original paint on it I believe
Slightly scraped but no holes. See pics.

Wet-sand the entire time. Start with 400, then 600, and finally 800. Duplicolor makes a product called Adhesion Promoter, which is a clear primer. It works great for plastic body pieces. Then your colour coat, and follow with clear coat. Let it cure for at least a week, then proceed with wet-sanding with 2,000 and follow up with rubbing compound and polishing compound. Wash and wax then apply to car.

Side note, you can use chemical paint peelers safe for plastics that'll make life a lot easier. It's a lot easier to paint a completely bare surface, versus trying to get everything level by painting over old paint. Also, if you know some place with a soda blaster that'd be ideal.
