Rustproofing SLA R170 rear arches

I am currently rustproofing SLA R170 rear arches, does anyone know if I can remove all visible grommets and rustproof the cavities or are there only certain ones I should do ? Any advice welcome.

Sorry gents, in my post above, `SLA` should of course read as `SLK` - I work in IT so I must have had a `Service Level Agreement` (SLA) on my mind at the time !!
