I purchased this without realizing that this was automotive primer, or even what that was. Has anyone used this on plastic or acrylic?

Yes my husband used it as a primer for his warhammer 40k plastic pieces. On acrylic I am not sure. I know he removed the previous acrylic work and some acrylic still remained but the primer went nicely over it, but if it is a lot of acrylic then I am not sure how great of coverage will be achieved.

is this a self etching primer?

I used this on the front of my horse trailer. It had been pitted by use on gravel roads and this worked wonders. I sprayed it last fall and it still looks great this spring.

Is the "red" really red? The cap in the pic looks brown.

yeah, it's more like brown... same color of the cap of the spray can.

Ive never used primer. Is it imperative that it not touch the paint/clearcoat of say, a car, around it?

It's basically paint so treat it accordingly. This primer has a VERY rough, almost gritty, finish. If you want a smooth finish you will have to do a TON of sanding!
