I have a large piece of Camphor Laurel that I have sanded and given a sealing coat to. I'm using Bonball Marine Varnish. I have left it between coats for 24 hours. This is the 3rd full coat today and to my horror, it has gone funny. Not cloudy but like its separated and got streaks in it. It's over the whole top.. What should I do and what caused this to happen?? it's only 21c here today and a slight breeze.. So I would not have thought to hot plus this is the same weather it has been the last few days. So disappointed. Many thanks for any help.
