While faffing around with the Crappy Coffee Table What Has Sentimental Value and Can't Be Conveniently Tipped Off the Edge of the Deck (CCTWHSVCBCTOED) I was looking for cheapest varnishes I could use on it, and by far the cheapest is BP's Timber Protect, e.g. this one, manufacturer's page here. However I'm very dubious of the "one coat" claim though, there's no way you could make a single-coat varnish work, and there's close to zero real information on it available on either the Bunnings or BP pages. Does anyone have any experience with this?
