Not my call or i have to walk out or be canned for not doing as owner wants.You do realize that 2K urethane is porous right? 20 years old, I can guarantee you that there are speckles of surface rust on the metal underneath that primer (at the very least) . No way in hades I'd spray over 20 year old exposed primer. Inside or outside storage would make no difference to me.
To each his own though I guess.
