Galvanised Boxer

Have just been having a discussion with my nephew regarding the merits of underbody rustproofing. I have read the existing threads on the subject and have decided on balance that it is a good thing. He tells me that his Boxer based conversion (not AS) has a galvanised chassis. I have a 2019 Fairford, can anyone confirm or otherwise advise as to whether this is the case on my van. I do seem to remember reading somewhere that after a certain date all Sevil vans are thus treated. (I have ordered the Waxoyl anyway ). Thanks, Ben
