Hi peeps,

I have a fibre glass bumper apron to go onto the rear bumper of my mk6 fiesta but it needs some work to get it to fit properly. Is there any specific method of processing fibre glass or is a block and sandpaper efficient enough? There is a section on the back that needs flatting down equally all around.

Would it be more simple to do the work on the bumper below rather than sand/process the fibre glass?

Your help, experience and comments are welcome. Thanks.
