Okay guys, as you can see from the pics the mold would not allow me to use infusion mesh over the entire mold surface due to some of the complex shapes.
The resin started okay but when the laminate was around 1/3 way I started losing vacuum on the inlet side, the bag became loose and resin flow slowed.

...as soon as the resin hit the laminate, everything behind the resin line (wet area) I lose vacuum, everything in front (dry) retains vacuum pressure.
Is this caused by vacuum not correctly distributed?
