Tried a solvent? like petrol or metho?

probably easier to just paint over it with black killrust?

Don't they say that the red desert dust (dirt) is the best rust proofing you can get as it doesn't take on moisture.

The best rust proofing you can do is getting underneath your car with a hose and washing it after an outing (especially after going anywhere near the beach!).

I also grab a can of inox and just run over all nuts and bolts and around suspension components etc. I have heard applying fish oil is good at protecting too.

There are under body treatments you can get applied to your car, but its still imperative you wash the car too.

Use a high strength degreaser to try shift the stuff on your chassis now.if it doesn't budge go straight over it. I use tektol in all the chassis rails and hard to reach places then Austek body deadner on all the flat stuff like outside of chassis rails and the underside of body
