Ah, so might this be why I had so much trouble with varnish
beading up on surfaces sanded between coats ? It was a few years ago and there should be a thread on the topic here somewhere after I asked for help. I did rub the surfaces down with thinner between coats, thinking the tack-cloth might be the problem but with little success.
I hadn't suspected the sandpaper to be the culprit but I was using some paper that was absolutely great, it cut really nicely and lasted longer than I was used to. I think it was advertised as lasting three times as long as regular paper ... ?
