^Yeah, that's going to be your best bet.

That stands for "Dual Action"

A DA sander works wonders quickly. If you don't have access to a large air compressor/system then you'll probably want something electric power

Just remember you cant just sand the car down with a DA and think your ready for paint. It will have high and low spots over the entire car. You will have to shoot the car with some high fill primer like a 2k product and then spray a black guide coat. After thats dry block the entire car. Then your ready for base and clear.

you want a 6" Dual action, there are expensive ones like hutchins and dynabrade around $150-200, then there are cheap ones for around $50 or less.
you want to use as low of a grit as you can (of it will take FOREVER) but make sure when you get down to bare metal you use a higher grit so you don't scratch the hell out of the metal. then like precision said you need to properly prime the car

why are you stripping your car out of curiousity? its a pain in the *** if you don't need to and will add alot of time and money to your paint job. you can paint directly over old paint if its in good shape.

I want to learn to paint my own car. My car isn't that new. It an old civic generation. If i use a Dual action sander it will cause high and low spots? I will look out for that. Can i use any other guide coat beside black?

Eyger

The color of the guide coat is irrelevant. The purpose of the guide coat is to help determine how "Straight" and flat the body panels are as you sand the primer.

Usually you would use black because it's a high contrast from your light gray primer. So when you sand over the body panels (With a block of course), and there are spots of black paint still left, you know that area in specific is lower then the rest of the panel, which would cause waviness in the final finish. Once you find out where the low spots are, you have to get it flat somehow, weather it's more primer and sanding, or even sometimes a skim of body glaze.
