Yeah that's basically what it is, forms a chemical bond to the metal and seals the surface. But only for very small areas. Just protects until the proper PT is applied.

Yeah true some nasty stuff in the aircraft industry. Bae used to use MEK for cleaning so nobody smoked near it. They spent thousands on new spill proof containers for Genkleen but it was none inflammable. So people smoked when using it. But the downside was if you sucked the Genk fumes up through a fag it turned into Phosgene gas, not very nice.

No it's not polish it is for treating alloy if the surface plating has been damaged. Most alloy sheet used in aircraft production was duralumin that corrodes, it has a very thin coating of pure aluminium on it to prevent this. If the surface has been damaged, Alodine solution is used to coat and reseal the surface. It leaves a light mustard yellow finish. Application materials have been know to spontaniously ignite under certain conditions.

Dude you are showing your age. :D I thought duralumin was only ever used in zepplins and little puddle jumpers.

I was just wondering what would happen if you left linseed oil on a rag. Must remember to ask Fett....;)

linseed oil is a live substance ( same as yeast ) before now ive seen a glazier wrap a rag full of linseed oil in newspaper and forget to throw it away :confused::confused:

the subsequent rag was left for 2 days the next monday morning we arrived at the site to find the house we had been working on burnt out :eek::eek::eek:

according to fire officials the fire started where the rag was with the explaination of the linseed oil self incubates right up to its flash point if conditions are right such as dry warm and a slight draft ;);)

It was a trade name for sure, but is now generally generic for alclad and aircraft alloy. As opposed to pure aluminium which is pretty useless for building aircraft with, other than for none structural parts. Just as every vacuum cleaner is refered to as an Hoover. Ok if you want to be pedantic Alodine is used for treating blended out scratches in the outer layer of alclad material. Dural can be heat treated to improve it's hardness or toughness pure Aluminium can't. It is also used as a temp repair on none coated Alloy were no Aluminium coat is possible, machined items for instance were the PT has had to be removed for some reason.

In that case Genkleen must be carbon tetrachloride (CTC) as used to be used in the old Pyrene fire extinguishers, great stuff for cleaning but bloody dangerous for putting out fires, kill the fire and yourself at the same time with the Phosgene gas LOL:eek:

Don't know what it's constituants were. It was carbon something or the other. But it was a bloody useless solvent compared to MEK evaporated too quickly. It has been discontinued now to preserve the ozone layer. Best solvent for cleaning aircraft was Bostik thinners we used when on the Jaguar. Smelled like peardrops and got you seriously ****ed after a while. Funniest thing was one night playing poker at dinner time. We used five gallon drums with the tops cut off as waste bins for the paper wipes and suchlike. One of the lads flicked a fag into one, there was one almighty bang and confetti was coming down for ages. Must have been at just the correct combustion level. Think they still used carbon tet til recently for dry cleaning machines. Maybe wrong but it sure smelled like it.
