Anyone got any ideas on how I can remove the surface rust from inside here without gringing the box section off?

Also I've been trying to remove some surface rust from my arches with emery cloth and one of these http://images.orgill...200/7088024.jpg
but I'm just not managing to get it all off no matter how hard I scrub. So any help will be greatly appreciated.

That pictures just looks like the cross member is full of the rotten bits of inner sill to me?

Maybe its just my eyes.

If it isnt, just get a hoover and hoover them out!

Then give it a splash of waxoyl/ similar before you put the inner sill back on.

Your right it is full of rusty flakes, but the surfaces on the inside of the crossmember are all bubbling up with surface rust as is the floorpan inside the crossmember. Look a bit closer.

Ah right, see what your saying now.

In honesty I would not worry about that at all.

It is only surfact rust and shouldnt turn into a problem, especially if you clean it out and get some rust preventative in there!

Polycarbide abrasive wheel or disc. Made of nylon cord with polyurethane coating impregnated with silicon carbide. Takes back to bright metal without damaging the metal. Bit expensive for large areas though (they wear out quite fast).

The problem with that approach is there's no way of getting a drill in there. I've considered how to do this with my Mk II, and have thought that a rust converter (Phosphoric acid of some sort, painted in as best I can, followed by zinc-rich paint again painted in as best I can, and lastly wax rust preventative would be the best for peace of mind - when you're doing all the panel work, to have some rust left in the car you know about, peace of mind means a lot.

Off the top of my head, one of those small long-handled rollers for painting behind domestic radiators?

You can get small sand/media blasters that you hook up to an airline, can you not? One of these might work. Other than that I was thinking a wire brush secured to a stick and get scrubbing, then etch prime and paint the inside followed by waxoyl.

That's what I'd do, but I'm still new to all this rust be gone business.

Yep you sure can, pretty good aswell..

I'd fix a bit of 40 grit paper to a stick and get the loose bits off the best you can, then spray jenolite rust killer in, let that dry, and pump it with waxoyl when the sill is on. Doesn't look like it's very serious yet, I think most cross members look like that inside, you get alot of condensation in there.
