But be honest, from that photo up there^^, can you really say it needs restoration?
I can't........mine is a one owner, magnum bonum, with quite distinctive features, possibly unique, I would never consider restoration. And it has a few chips, that only serve to remind others of it's history.
In my view, some people restore bikes that don't really need it, ....and have no appreciation of 'patina'...no matter how many (much?) resources they have.
Once it's gone, it's gone.......it might be shiny though.
Like I said though, it's his bike, and each to their own.
