Yuk! great oportunity to clean it all up Rob. When we chatted I was going to mention about supporting brake calipers when stripping down the front but see you have removed them. If you whip off the hubs you have a great opportunity to paint protect the stub axles before re-assembly.
When I viewed my car in build as it was entering the trim shop, I noticed these already had surface rust. Queried this and was assured they get painted. This translated as a smattering of underseal in one or two places
