My roof was looking a little shabby so I thought I would re-colour and reproof it. followed the instructions to the letter not in direct sunlight started from the middle and work out 2 coats of dye, roof now looks worse than it did in the first place :x
anybody got any ideas how I can undo the damage I have done and try and get it looking black again
