Hi,
I'm totally new here and I'm certain I've just used the wrong product!  I made a tray for my wife and attached small photos to it.  I used glasscast10 and whilst it looks great, it's quite soft?  It would seem I would have been better using glasscast 3?
I guess my question is, would glasscast 3 have been more suitable, and if so can I apply a coat on top of what I've already done?  To clarify the tray will be used as a tray carrying crockery etc.  Many thanks in advance.
