Not really, bear in mind I'm in Cyprus.
Follow the instructions to the letter. The one I use needs to be carefully measured at a 60/40 ratio by weight and then mixed slowly for 3 minutes. My first efforts were disasters until I got a timer and mixed to the second. I use a thin flat offcut of wood (12" x 12" x 1/16") in a battery drill on slow speed. that way you dont introduce many bubbles.
its a 2 part epoxy that dries crystal clear and is self levelling (takes 2 days to be hard enough to handle safely, another couple if you want to drill). Take care where you pour it, I have ruined my workbench top with overspill since doing these. But my bench top is only 1" planks laid over a solid base, so I can just rip the top layer off and resurface .I should have used that very thin painters plastic dust sheet to catch the run off.
