Not the most exciting topic I know but can anyone recommend a long lasting exterior wood paint I can use on a new tongue and groove shed. Looking for suggestions on brand and colour, thinking of possibly a green, blue or grey colour. Have seen Protek Royal exterior paint but it is £65 for 5 litres and £65 for the primer too. I am not sure if one pot of each will even be enough. Not sure how any of these paints will look after a few years, how they weather and how easy it is to repaint. Would I need to rub down, prime and repaint every few years? Any experiences or ideas would be welcome. Thanks
