I've been in the auto paint business for many years. Red can be a ***** to match. Any of the paint companies only promises to provide a "Blendable Match". Since there is no blend in this repair, the painter has to tint to match and get it dead on.

A *lot* of painters get lazy with bumper covers, since, most often, they don't match the rest of the car anyway. As far as I can tell, the XFire bumpers *do* match... so, again, the painter is going to have to get it dead on.

He'd do best, if possible, to paint and blend the repair area. He would scuff the entire bumper cover, paint and blend the repair area, the clear the entire thing. That would give the best results (other than a gnats *** color match).
