Afternoon,
I have bought a bulk of polyester resin and catalyst as my weekly shop to the local car repair shop was becoming too much. The catalyst is now a liquid instead of a paste, however it works fine and goes very hard like normal.
I was using it again today and instead of going completely hard it has gone rubbery. I am pretty sure I used the right measurements as they were the same as last time. What am I doing wrong? Too much catalyst or too little?
Here is what I am using if it helps:

Resin - http://www.amazon.co.uk/gp/product/B006DY1QXW?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
