I am making a wooden bowl and used epoxy and LPU Top Coat (www.systemthree.com) to seal it. I lightly sanded between each coat but is there anything I could do on the last coat to help the "smoothness" of it? It is pretty smooth now but there is an occasional slight brush mark, small bubble etc. I was thinking maybe steel wool then buff it (with what?) or something. With other non lathe projects, with varnish, I don't touch the final coat at all but I was hoping there would be something someone could suggest for this. I talked to System Three guys and they say it can be buffed and polished after it has cured completely.

I have never buffed anything before so what do I do I need to do it? Will that bring out the slight brush marks and things like that?

Thanks
Darren
