Currently building a timber built car-port. The roof will be covered with a Polycarbonate sheet system and I will be covering the facias and any timber directly exposed to the elements with GRP. On the inside however I want the wood to be it's natual colour so trying to choose the best varnish/preservative/oil. I want it to be low maintence and I don't mind spending some money on a decent coating. Is a standard polyurathane clear varnish the best product for this purpose?
Many thanks, Lee.
