I was going to order mine but found it by accident in my local hardware store.
Dont think the autoglym will do it, i have that kit and though i dont have any mould i've a feeling it wont be enough to remove it, maybe treat those bits first with a product for dealing with mould and then give it all a go over with the autoglym kit? Someone, sometime has put the roof down when its damp
V. important to follow the instructions on the glue, dont do what i did when i used it on something else, not read and then wonder why it didnt work
Wonder if this stuff is any good?
