Front bumper cracked, any repair available ?

My post is about the rear bumper but it may help you.
A year ago i hit my rear bumper on a cart full of bricks. The cart stopped the car but it's handles hit my bumper deeply by creating two 2cm in diameter and about 3cm deep holes. What i did was to add 3 layers of fiberglass putty on them and then sanded them. Half a year later and it's still in place although I didn't do anything from behind the bumper.
