so you say my error was to quickly to open in full vacuuming and let resin to flow? and 10 min to degass only? yes?


No.


i thought maybe bag was not pushed to a corner that why bubles trapped - strange i checked and gauges showed good vacuuming and side where good.


Exactly. The fabric wasn't in contact with the mold surface in the edges and corners, there was an empty space between the fabric and the mold, that's where all the resin went, starving the part and trapping a lot of air bubbles.
