acetone in a spray bottle. that sounds so dangerous.

As mentioned a heat gun works, but you have to be careful. too much heat and youll create a cluster of epoxy vapour bubbles and make it worse. I also keep some acetone in a spray bottle and mist the coated part, it will temporarily thin the epoxy and the bubbles will pop. The acetone evaporates almost instantly.

Not really if you are going to apply it by brush then you will introduce air back into the resin simply by brushing. Brush on the resin as carefully as you can then go over the part with a heat gun and you will see any air bubbles rise to the surface and "pop"

Is it worthwhile degassing my coating resin in my easycomposites vacuum chamber before brushing it onto my part?

Thanks in advance for your advice.
