Hi, I have installed a few window cills made of some resin like limestone, like cream in colour, and noticed they stain very easy, and was told to use Stain-Proof to paint over them, like a varnish so to speak. Stain-proof costs a fortune and before making a mess of it all, would like to know, has anyone got any experience using it, or any other agent to protect them?
