Hi Guys, My brother managed to get a lot of bitumen paint from where he works, so decided to go with using that for the back and sides. Very happy with it, forms a nice rubbery sort of finish and no doubt will keep things nice and dry. Getting behind it wasn't so much fun (especially after all them mince pies at Christmas...) Now as I have so much of this gear left over. I am tempted to coat the roof too (currently has felt on it but not the greatest quality) so keen to do what I can to prolong the life of it. My question is, if I coat the roof in this stuff. Come summer will the loft get too hot??? (Remember this bitumen paint is black). Any info/guidance much appreciated. Cheers, Pete
