Duralac - which product is best/correct?

Sat May 07, 2011 7:57 am

Just doing some general fettling on my car and I have an old tin of the Duralac sold by Eliseparts:

This just looks like paint and goes on quite thin with a paint brush although the website states "Simply smear a layer between any 2 surfaces not only will it arrest the corrosion process it will act as a very fine thread sealer and enable easy bolt/nut removal in the future."

Looking on some of the boat websites they seem to offer this:

which looks more like a paste to be applied in a similar way to say copperslip.

Just wondering if I have the wrong product now?

Steve, I think you're ok it's still the same stuff regardless of the container.

I have a tin of this and was wondering what does this do that a bit of grease won't do?

Thanks chaps.

Just lookig up the "active" ingredients - seems to be barium chromate.

Barium chromate is a fine light yellow powder with the formula BaCrO4.

There are a few uses of barium chromate:

As an oxidizer and/or burn rate modifier in some pyrotechnic compositions, especially delay compositions.
As a pigment in paints, ceramics, coloring glasses, fuses, and porcelains.
[color:#CC0000]As a corrosion inhibitor to prevent electrochemical corrosion at the joints of dissimilar metals.
[/color] In safety matches.
In metal primers.
In ignition control devices.
As an initiator for explosives.

but not sure why it's better at this than say grease...

Barium chromate ..... better at removing excess cash from pockets when compared to grease !!

I was asking mainly because when I took of the engine mounts, subframe and the balljoint brackets on the uprights, there was still corrosion in there despite the duralac.

It was like that when I bought it. There was quite a bit of it and the rest I have no idea.
