We have all hardwood window frames which are in good nick other than the old varnish starting to peel. They are mahogany stained and varnished at the moment but I was hoping to paint them cream. I was wondering whether anyone had any recommendation for good exterior wood paint? Also any advice whether I need to completely remove all varnish (please god no....) or just give them a good clean and sand off the flakey bits. Getting myself very confused about primers, undercoats, gloss etc. We are South facing and live in a very exposed (read windy and rainy) location. Any advice very gratefully received!
