Jeff, as a newbie, what is 400 grit? Also, what's the best way to bleed the lines and how and when should I go about doing that? Should I drain the resevoir first, then take it apart? I have all of the manuals for it (just not handy at work) so I'm sure it will walk me through it. But sounds like you have it down, so any walkthrough would be great. Thanks for your time.
