Painting back bumper

I'm painting my back bumper I've sanded it down with 100 grit paper really well, and want to know, do I put this flat white primer on first and then the paint cans I have? How many coats of each? And any tips! Thanks in advance!

 

I'd just plastidip it

 

I'd read the can.
Should say how many coats, how long between coats, if sanding is needed, etc.

 

Honestly I spaced it on that because I didn't like the plasticity job on my grill, but if the paint turns out bad I'll sand down and plastic it!

i know but I'm not sure on if the primer goes first or I should just use the "Paint+Primer" or it goes after or what

 

Primer always goes before paint.

 

I plastidipped mine. After a full season, it is holding great. Surprised actually.
That P+P you got is a flat finish. Won't look much different from the primer. Do the primer first, one coat will be fine, then do about 3 of the flat stuff.
That should do it.
You may want to try plastidip first. It is an easier route, if you mess up.

 

Factory primer is grey. But why are you priming? Are you working with a brand new bumper? I would get aeresol primer and Toyota Super White from a company that will send you the correct coded paint (found on your door jam). I wouldn't just go to Home Depo and pick some shit off the shelf.

DO NOT attempt to paint over chrome.
