Can anyone tell me please if Zinc Phos primer goes off? - I have a tin that has been in the garage for about 15 years which I have just unearthed! I had started the tin.
Cheers,
Ian

If it's still liquid I can't see why it wouldn't be okay - give it a good stir and paint a bit on something scrap and see if it dries and sticks ok.

A REALLY good stir, the zinc will have settled on the bottom of the can like rock forming silt.
I've got a stirrer that fits on an electric drill that would be ideal for the job.

Thanks guys,
I will give the tin a stir or two tomorrow and see how it reacts.

you may find it has a reaction when on metal
and cracks and crazes. try leaving tin upside down for some time or soak tin in boiling water to get the properties to seperate

Thanks irmscher
Since posting the thread I haven't managed to get back into the garage so will give your advice a try before opening the can and giving it a stir up. I really only want it to hold some panels that I have been working on before I get around to painting them. Will probably sand back the primer then and start again when all the panels are ready.
