Epoxy pouring advice

[Wobblycogs]

Is it just me or did that guy go a bit over kill on the epoxy for that pour, he must have made up enough to shoot the video a dozen times!

Anyway, as far as I know that blue tape is just a decent quality masking tape. Loads of the woodworking videos I've watched use it and they all refer to it as blue tape (in particular David Marks, he gets through a roll a show I reckon). I seem to remember seeing it for sale at ScrewFix a while back.

I used epoxy to fill knot holes in pieces of wood a few times and will usually make a dam with regular masking tape e.g. covering the back of a through knot so all the epoxy doesn't run out. The epoxy doesn't stick very well to the glue side of the masking tape but it's a long way from perfect. I always sand it down flush so I've never bothered to try and make it stick less. Talking about sanding it flush the best tool for this is a belt sander and that would be perfect for taking off the meniscus with the minimum of work too.

It would be fine on a piece of wood as you described but if I had used my belt sander it would have completely knackered the epoxy job, too aggressive, can't see what's happening enough, not enough control on keeping it level. The file route is the only sensible way I'm sure.
