Vatcan goes off, I just thought you might like to know this

I got mine out when I was tarting up my new (to me) propex unit. It had "set" inside the bottle despite the cap being securely on. I bought it about 18 months ago and only used it once ! = Very annoying

Silicone RTV gasket stuff does it too, as does the expensive "SuperGlue" I use when building my model aircraft.

Grrrrr

as does sikaflex, TIgerseal, Polyurethane glue...... its very annoying.
Sometimes I put the bottle into a ziplock bag, suck the air out and seal it, if think I won't use it for a while. And if you throw a handful of dry rice or pasta in there too, it helps a bit.

Yes it does, thats why I always recommend Vactan is bought in smaller bottles. Shelf life is about one year. Tends to last longer in cool conditions too.

I just binned 2 litres of it
I did find though, that the vactan used to flake off if too much applied. So I switched to dinotrols aerosol version of it.

Handy info for someone whose just bought two litres! Got it primarily to fit my Propex and various other bits.

I bought 2 litres to save on p&p!

If I keep the second bottle sealed until needed should that have a longer shelf life than the one that I've opened?

Glad i took note from the DVD that a small amount of Vatcan goes a long way. I got 500ml bottle done the van, gave some away and still have half left.

Thats the way Jonno. By the way, liberal coats of Vactan are not the way to do it. It only needs to be 40 microns thick to convert and protect - ie very thin coat. More does not do a better job.

One litre does 8-9 square metres!!! If you've got that much rust, sell it

Oh bugger, I purchased some last summer, and its remained unused, still in its bottle. I did noticed last time I was down in our basement that the top half of the bottle is brown now, with the lower half white. Please tell me I can simply shake the bottle and use?

Shelf life of a year? Bugger me. 500ml bottle too

Give it a shake. Should be ok.

Will give it a try, but unable to use it till the temperatures rise a bit more here. Snow snow on the ground too.

anything that 'sets' as a deliberate part of the process it performs is going to dry out or go hard once air forms more than an insignificant proportion of the overall container contents.

Although with Vactan and Ku-Rust and similar products, just dipping the brush back in the bottle you just used to apply some to the rust with will effectively shag the entire bottle.

I've had a bottle of KU-Rust since 2009 - still good
