It's cool all flaked off like that. I owned a 1980 Blue Team goose that had about 85% of its OG finish. Cleaned it and eventually sold it to another collector that wanted a complete "Original". There were times I wanted to restore it but I didn't want to affect its future market value.
Hard call on the restore. If you're keeping it and/or not concerned with "survivor" market value, then restore it.
I've heard that One of the biggest collectors in OZ, restored most of the bikes in his collection so what's the big deal? He's not really selling any of them.
As for the bmx museum. Try offering that one up to any of those guys as a trade for a restored one and see how far you get.
