Putoline PPF-52... Corrosion X.... Viable ACF50 alternatives?

[Dead Eye]

On the subject of anti-corrosion protection, I used something on the body of the turbo unit on my old Kwak. It came in a plastic bottle, about a litre. It was a thin-ish liquid, blue-ish white in colour, which I painted on the casing with a brush. It dried to a glossy blue-black colour and went hard as nails. The turbo body was cast iron, and so always was coated in a layer of rust (not a problem because of the thickness of the case, but unsightly) and very thick - had to be like armour to withstand temp (turbos glow bright red hot in use) and potential failures (spinning at speeds of up to 200,000rpm a failed turbo impeller could do a lot of damage). This coating I used was very durable - in fact I saw no signs of any kind of deterioration for the rest of the time I had the bike, and the unit was positioned where it caught a lot of road crap. I thought it might be the ideal stuff to coat the EXUP part of the exhaust on the gen 1 , but can't for the life of me remember exactly what the product was. Sound familiar to anyone?

Sounds like Kurust to me - can get in Halfords. I bought some for my old Mk2 Golf... but that had a bit tooo much rust to cure :\
