Afternoon folks.  I've done some complex shaped parts recently.  Obviously I used lots of pleats in the bag so I had plenty of bag to get into all the returns.  The downside is that this has left some ridges on the moulding where the creases were.  Is there anyway of stopping this?  I considered using the stretchy bag but this blocks up the mesh so I considered a layer of peelply over the mesh etc.  Thought I'd ask what everyone else has done.

Very thick laminates it can be the fabric itself - as you say if it hasn't been debaulked, there is a tendency for slack in the fabric to bunch up when vacuum is drawn.
