This is a bit left field and my apologies if the post should not be here but it is possibly the best fit as laser machine operators who use varnished wood panels as a raw material source need to get the panels varnished. Does anyone varnish their wood and if so do you use a machine? What type? I am considering sourcing a roller from China so looking for some recommendations that will varnish 800mm x 400mm panels up to 5mm thick.
