Just chewing this one over, so after some advice.
Internal panels, doors and such, where there may be surface rust on the internal faces and/or seams, is it best to pop a weak solution of something like phosphoric in there first, let it dry and pop some oil/Waxoyl or similar in to cover it, (would the solution need rinsing out first?), or just pop oil/Waxoyl in there as is?
