Yooo, so i bought a set of 16v bumpers for my 6n yesterday and i really wanna smooth the front, all apart from the center bottom grill. how would i go about it? fibreglass? filler? I'm an amateur and need help!

Get a top section of an 8v rear bumper, cut out the recess and plastic weld a section of the rear in.

As for the grills, same again really. Cut sections out the rear bumper and plastic weld in.

Don't just fill. Guaranteed not to last that way.

From when I smoothed an 8v, works on the same principles.
