I bought some glasscast a while back but  I don't remember it being "split" into one of the current grades...10, 20, 50 etc...it's not got any such label on the packaging...which one is it likely to be?

I'd like to get the same one as it's giving me excellent results...it's a fantastic product for coating 3D printed prototypes printed in PLA - even with fairly coarse 2mm layers, the Glasscast gives a beautifully smooth finish in a single coat and despite being quite low viscosty and a reasonably long set time, doesn't drip very much at all if I'm careful not to apply an excess.

Not sure if anyone else is using it for this, but I think it's really good!
