The picture is from the right ramp flap on my IJ pinball machine (sorry about the flash but you get the idea of what I'm dealing with). I was going to replace it but after reading about removing the rivets and then re-riveting, I am starting to think about re-bluing the ramp. I don't have any tools to put the rivets back in with and am worried that I could crack the plastic if I go with one of the less expensive riveting options (using a rollover die and hitting it with a hammer). Additionally, these ramps don't seem too easy to come by.
So, my question is has anybody salvaged a ramp flap that is pitted like the one pictured? If so, any hints would be great. Of course, I am open to any ideas that anybody has.
