Hey RX7 Lover, jsut wanted to hijack here and mention that I'm also a rotary fan. I have an 1985 (1st Gen) GSL-SE witrh the 13B. I also have an RX8 on order...
Anyhow, the switch blade isn't the biggest hooking ball in the world (it's on the lower end of average).
If you want to try scotch brite pads, hit the auto parts store. I got a number of grits at a NAPA store, including maroon (320g), grey and white (800 and 1200 I believe, off the top of my head).
Good luck... and zoom zoom!
