Hi Graham, the surface looks like it could do with a light sand and I would urge you not to as that could risk damaging the coats already laid down.

The best part of using TO is that it eventually will flatten out the surface the more coats you apply, almost like those epoxy resin videos you see on You Tube but not as fast as it takes many, many more thin coats to get there whereas epoxy is just one thick very fast curing nasty toxic mix.

I share your pain with the binding and avoid it wherever possible. So much prep required to try and minimise stain bleed which seems to happen most of the time.
