OK, I'm confused.
The only galvanising I have come across is the hot dip type, as used with farm gates, water troughs etc. It is not a process I would put anywhere near a bike frame for too many reasons to go into here.
There is a liquid galv process, Galvafroid (sp?) is one brand I know, but again this is for iron railings and garden gate protection, contains a lot of zinc and weighs a ton. It is also very expensive.
If you are looking for a cheap robust finish, then powder coat would do, but it would be a shame to powder coat a rarity like the Overbury's. I would be inclined to get a decent spray job done by a paint shop that really knows bike frames. I have a Roberts frame that was re-sprayed by Bob Jackson and it is excellent. I believe their prices are good and their turnaround is fast.
