Now the Stylus is sold i have started on my next project which involves restoring (among other things) an early Mazda RX7. The car isnt too bad but still needs a fair bit of work on the dreaded rot. Any tips or recommendations on products that actually work or how to deal with it would be much appreciated.

From Dec 2011 practical classics:

Rustbuster FE123: 10/10
Hydrate 80: 9/10
Gravbille Heavy duty rust cure: 7/10

I'm using Vactan with excellent results. It's very similar to a product called Neutra Rust which we used on ships in the 90s.

thanks guys. All the ones for sale on ebay seem to say they are acid free.

Did you want to stabilise the rust or remove it?

i suppose i want to stabilize the surface rust and remove the serious stuff? Does stabilize mean turning the rust into something that is no longer rust? thats what i thought the rust converters did?

I would recommed the detox Gel made by Bilt Hamber as a rust remover its worked fora friend of mine who is a coachbuilder and is restoring a honda prelude. ive also used it with the mtal protection and zinc plate. The sutff supprosingly is water based and can be disposed of easily
