Rust in E30 sunroof cage

I recently removed the sunroof panel from my E30 and noticed lots of rust in the rear corners of the sunroof cage. The rust was flaking badly but doesn't appear to have penetrated through the metal yet. What is the best course of action to take? Should I spray the area with Waxoyl or is there a better solution. I'm tempted to remove the headlining but is this a good idea or not?

quite a common area for rot even on thee most mint E30's .. like sporty1 has said, you'd be best to remove the headlining and see the extent of any rust/rot leading to the rear end of the sunroof channels.

hope it's not to bad  

Get an angle grinder to it an remove the whole sunroof cage

That's what I'm doing with mine.......Although it is a track car....

 

The headlining is a pretty tricky job to remove. Windscreen has to come out and possibly rear 1/4 windows if they don't open...

Dealer's your best bet.
