Hi all, i have some wooden window frames which i need to rub down and repaint. There are some areas where the wood has weathered and/or paint has flaked off and wood weathered. In these areas the wood is a little bleached and maybe a bit brittle though not soft/rotten. Is there anything i can use as a base coat before using undercoat and/or white gloss which will help preserve/strengthen the wood?
