Hi I'm having some real problems achieving full vacuum when I'm bagging. I've found that the flow mesh is puncturing the bag, I've tried adding a layer of peel ply on top of the mesh and this helps a bit but I still seem to get leaks from pin holes out of 8 attempts to mould the part I've only had sucsess once (unfortunately I had a stray strand on the visible side!😠) any help or tips would be very much appreciated because as you can imagine I'm starting to loose heart with producing the part. 

Cheers Tony
