I put a fairly concise how to here. The draft of your form is really working against you. I just watched your vid and if your glass is at a similar place as far as setting goes use a chip brush if you have any to tap it down and remove as much air as you can. The resin will set up and get stickier. As it does keep tapping the glass down. You should be able to get a lot of it down with a bunch of babysitting.
