That stuff is almost certainly the same as this:

Wessex resins tote this as a "coating resin" for table tops etc. but it is much more useful than just that ...
It is a very tough and very clear coating resin, that can be brushed on and will self-level out the brushmarks quite well.
It leaves almost no trapped bubbles, even without using a heat gun ..
BUT: It will not properly wet out carbon fibres, and it will trap airbubbles inside fabrics... so in effect it is ONLY a top coat ..
Also it will flow off steep sides ... but still leave a nice thick coat.
"Sapere Aude"... Dare to KNOW!

Do not adjust our mind, theres a fault in reality :-)
