Different plastics will be gripped by the resin differently depending on slippery surface, porosity, roughness etc so you would expect a slight bit of difference.

The product you currently have has been renamed "GlassCast 3".

In essence soon after relasing the original GlassCast  3, it was clear from customer demand that products with a thicker casting ability would be needed and we set about developing the 10 and 50 products which were recently released.  The number represents the typical maximum thickness we would expect the resin to be used at.  This means the GlassCast 3, as the original, is still firmly aimed at the surface coatings such as penny floors etc.  Thicker casting such as jewelry etc would typically go for the the GlassCast 10 and the GlassCast 50 would typically be used for thick river tables, furniture casting, thicker jewelry etc.

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!
