Two Box Gutters Badly LeakingSteven Dickinson
We run a small charity in France. We have a small house where all kind of people find rest. The two boxgutters are badly leaking. Professionals in France swear by zinc and tin.
I have little choice but writing to you having noticed your pedagogic YouTube channel.
It would really be of great help would you find time to answer my question:
Is the second white coat a UV protection layer? If yes are you happy with it?
Keep up the good work.
