Trying to avoid a body shop any suggestions would be great, its a little spider crack from a wreck before I had it.

You could try to buff it it may hide it a little it did on my bumper but the only way to really fix it is to sand it all the way down and prime it real good and repaint it. Because the paint is actually cracked so is the bumper a little but thats what the primer is for it fills in the little cracks in the bumper its self.

I'm afraid you will have to sand and primer and paint to make it right. I tried wet sanding and buffing mine didn't look much better

that is the paint itself that is cracking maybe down to the primer
it will need to be sanded out primed and painted
