While disconnecting my boat from my FX, I failed to make sure the trailer's tires were blocked. Well, once the coupler let loose from the hitch ball, the trailer rolled forward and the tongue hit the textured black plastic on my bumper, just below the painted section. It left a nice indent about 2" wide and 1/4" tall. Do you think there is any way the appearance of the dent can be minimized? I was wondering if gently heating the area might help but want to ask someone more familiar with working with plastic...
