Few more pics of todays progress.
Basically just sanding down and treating the surface rust. Nothing too major. Had already removed all the wax with a heat gun.
As for the backs of the inner wings instead of removing all the seam sealer down to the metal I have removed it where it has lifted due to rust, treated the rust and reapply sealer then will be some stonechip then paint. Will adopt this way when I do the underside.
