Oh no, the tin lasts a long time. And I think any old solvent would do to thin
the stuff if it had dried up a bit. Let it get good and warm give it a good
stir, and off you go.

I meant that the bitumen paints I've used all have weathered off fairly quickly.
There's a few that supposedly last a lot longer: some sort of water-soluble
acrylic roof paint, or two-pack epoxy stuff. One look at the label: coverage
rates and the price tag mean that I can either put up a new roof for the money,
or keep the money and slap paint on every two years or so.
