- Depends what you want to achieve; converting existing rust to
- something more stable, or preventing non-rusty areas strating to
- rust.
-
- For existing rust, phosphoric acid will convert rust to black iron
- phosphate, a good base for paint. You can buy this stuff off the
- shelf as "Jenolite", but practically any commercial "rust eater" that
- is pink coloured will contain it. It's much cheaper in bulk though -
- I get mine in 5 gallon drums (but then I do have 2 Fiats & a Lancia)
- for the price of 3 normal 1/2 litre bottles. Wirebrush the loose
- stuff off first.
-
- For continued protection, Waxoyl or similar is recommended. This is a
- paraffin wax in a spirt solvent base, and is applied by a spray. It
- only flows on a hot day, or after being stood in a bucket of hot
- water, and the plastic sprayers are useless. I use a compressor &
- paraffin/underseal spraygun with a long nozzle, but you can even
- brush it on. What you can't do is paint anywhere near this stuff has
- been applied - steam clean it off first.
-
-
- Neither of these magic sprays will work to preserve bare metal - that
- needs paint, and not just a cosmetic topcoat either. I use Hammerite
- or Smoothrite for covering rust spots until I have time to do them
- properly - it works well as a single coat is long-term rustproof, but
- it looks like shit.
