I've just installed 4.2 metres of 280 X 2000 mm shelving. It's only whitewood, and it's not a thing of beauty, but I'd like to stop it rotting or getting eaten by woodworm, so before I load it up with the usual workshop junk, I want to put some preservative or varnish on it - preferably things readily available, effective and quick-drying. What do the resident experts recommend ?
