In the process of shortening my struts i got distracted and forgot to take out the shock before starting to cut, im a complete "ass" i know. And by the time i knoticed it was too late

. from what i gathered only minimal fluid was lost, But i know there will be air in the shock now.
Soo is this shock capput or could it be welded up and saved somehow?
I know people have completely stripped down shocks before but i wouldnt know were to start
Cheers
Carl
