Proseal out of date

[Sam Buchanan]

That guy must have a lot of relatives.....I know one of them, too.

As an experiment I made a test article of 10 year old Proseal, new Proseal, old proseal with old hardener and new Proseal with old hardener.

The old Proseal had never been refrigerated.

The hardener made no difference at all. The old Proseal took about twice as long as the new to set up.

I kept the test article around for a year or two. Besides the color of the different mixtures there was no difference in texture or adhesion.

I would still use new Proseal on a tank... just because.
