what is the best method of rust treatment when removing rusty bits? For example if I cut out a rusty sill section so as to weild in a repair section but there is surface rust inon inner skinspanels do I just treat with rust converter and paint ? I am refering to areas of metal that are solid but have surface rust what products ? paint ,convertors.

There is stuff called Galmanet - pretty sure that is how it is spelled. Kills rust good

All I do on a bit like that is rub it hard with a wire brush then paint them with red oxide.

Classic for that is the inside bottom of the doors, making sure you don't block the drain holes.

Hear is some advice from a panel beater.

I am not convinced that rust converters work, I have not seen any proof of it working.

surface rust can be easily removed by sanding back with course sand paper and then priming with an etiched primer or a surface primer.

Holes can be welded up, ground and filled with fiberfill, bog and then primer. As long as you prime and body dead the area inside.

Hope this helps

I would take the paint off with stripped then use a portable snad blaster to blast the area to make sure all the rust is gone.
also gets the dirt off so welding can be made easier

after you have repaired the section and r looking for a good rust preventive try LANOLIN spray. should get it from any auto outlet and is fantastic for rust prevention.
buy a few cans and do the whole car!!!!!

Ive just found out about Lanolin spary yeah got to agree it works GREAT...

A good way to prevent rust is with cavity wax the product i used is called cam wax.......mix it with fish oil and it will set in the body this will not run out like fish oil and give protection forever.....

Rust converter contains phosphoric acid - buy a bottle or that instead and it will last a lifetime. The idea is that it converts rust (iron oxide) into iron phosphate, which is not as powerful an oxidant, thereby halting the spread of rust. Having said that, it's really only good for touch-up jobs, allowing you to paint over the area without cutting the whole lot back and respraying. If you are doing a re-spray, it is far smarter to clean all rust affected areas back to bare metal (plus a bit more to make sure,) then immediately spraying on a primer.
