Sub frames

[John_S4x4]

Am I correct in thinking that the subframes also rust on the inside due to the holes/condensation ?
Powder coating would only cover the outside. Would a dipping process (zinc galvanising?) be better ?

I think this has been discussed before and as galvanising is a hot process there where concerns of distortion, I still think the best method is plenty of waxoyl or similar inside and out every year
