Morning (here anyway) gents,

Does Cermark paste have a shelf life after opening?

Did some engraving about 8 months ago, didnt use all the tub but screwed the lid on tight afteruse. Went to use it this morning and found it is quite hard in the bottom - it seemed to mix up after a fashion but it doesnt seem to the the same as when 1st opened (am I expecting too much?)

Cheers,

Graham

Nope, DNA just evaporates. Add more, and thin back out.
