[NRVR-Members] Glassing - Best suppliers for peel ply?

[Thomas Tweeks Weeks]

Yeah.. I was looking at Fiberglast Bob.. but they are a bit more $$. And Jordan turned me on to US Composites (who I hear actually produces all West Systems stuff):

(suggestions welcome)
 
I haven't had a real need to bag anything yet.  Most of my projects are fairly small, and since I'm doing this tip-to-tip job.. I'm thinking about just doing peel ply, some bleeder (purely for absorption) and maybe sand bagging for constant pressure (since I don't have a vacuum bag setup, and doing it on partial a tip-to-tip seems like a pain).  
 
Comments/suggestions welcome though.

I have done vacuum bagging of plywood fins but before they were installed. I used Teflon peel ply which is expensive but works really well. I did a sandwich of plywood fiberglass peel ply and bleeder cloth. I’ve used Fiberglast but there are other options.

  I thought you were using plywood?  Recall my
  fins vibrated into shreds due to large size.  Are you
  reinforcing plywood with carbon fiber or are the fins
  fiberglass?  How many layers and are you doing anything
  special to reduce vibration?

   Doing
   a non-bagged (probably just
  weighted)  fin, CF, tip to
   tip job on my 5.5" Black Brant.. and
  need some
   supplies. I'm using West Systems and a
  course weave CF
   (not for looks.. it's just what I
  have).  

   Also.. I would love to hear discussion
  on preferences of the
   various types of peel ply.  The nylon
  kind,
   plastic/rayon/paper kinds, or the kind
  the red lines in
   it..
    
   Do
   you use bleeder cloth (for catching
  excess epoxy)?
