Be very careful with any alodine, it's chromic acid and is quite toxic. Safety glasses and latex gloves at the bare minimum, and any rags or material that comes into contact should be flushed with water immediatly, it has a tendency to ignite as it dries out. It's really good stuff but just needs to be treated with respect. It also helps paint stick to aluminium. I won't paint ally without using it. Selenious acid works best for spot touch ups on magnesium, a proper chromate bath is even better if you can find one.

To be honest I have used Alodine for ages and never had any issues with ; you are talking about Acid ? Alodine never was eating any part of material I plunged into ? I bought Alodine in small plastic bottlle to mix to warm medium water and this was send by the supplier by post ? So am wondering really if it was so dangerous you are describing ( it's complety different than nitric acid for example !! yes this one is really dangerous )
I was using Alodine to make any aluminium part I built a sort of yellow gold color ( before painting) and just using glove not to have thingers yellow too !! and had some days some on hand but really never feel any attack ?

But you probably know more ; so it's better to follow your precautionous advise ..... I will do next time now for sure

Interesting you are speaking of Chromate bath ; is this one that makes parts black ? Will be very interested to know more about this ( Can a private people use it easily ?)
