I'm repainting my hatch and doing all the body work myself. I've pretty much gotten all of the dents in the sheet metal either popped out or filled, but I still have some dents and chips in the front and rear bumpers. What is the best way to fill these? Is there a special body filler for plastic?

I found a little bumper repair kit from O'Reilly that includes a little mesh screen so thats what I used.
