Help Fixing Unlevel Scrape on Bumper

I drive a 2006 Honda Civic Si and have an unlevel scrape on the front left bumper. I've also got a cut from backing into a license plate of another car on the rear bumper. Is it possible for me to use the same wetsanding procedure to repair the scrape considering the bumper is plastic? I've sanded it down but the bumper appears to be crater-like. I do not think I can use the capilary action method to fill the scrape with touch-up paint either because the scrape is not sharp but very gradual.



Here are the pictures:

It will take several spray paint and sand applications to level it up, don't rush it will take 2-3 days to do a good job !



I have done many repairs like that and you can't tell the scrape was ever there !
 
Is the repair only possible with spray paint? I've already read plenty of threads on repairing scratches but nothing really in particular to the bumper.
 
Here are three threads that might help you out with different tips and techniques:

Be careful wet sanding or you'll go through the clear coat. Is there any reason you sanded before you built up the glob of paint (last picture)? Also, what grit paper were you sanding with?
 
I sanded before the built up glob of paint because my dad did a bad job of touching it up after he scraped it. I didn't know about it until later, after he had decided to touch it up himself. I used a 800 grit because the 1500 was not happening. I probably went through the clear but I figured I'd have to start all over again because the scrape had originally gone through the clear. I was thinking, touch it up again, sand it, then put a coat of clear over it.



I've already looked at the first 2 posts you've refered but none of them can really give me an idea of what to do for the crater-like scrape on my car. I appreciate the help!
