[C320-list] Water lift Muffler

I would recommend that you add milled fibers to the West Systems and clean the area well with acetone after you are sure it is 100% dry.
Good luck!

My plan is to grind out the loose glass and fill with the West System.  Also plan to fill all the screw holes. If there is something out there that will work better than the west system please let me know.
