I'm not great at trad or insides, and struggle with drips on carpet.Also interior roofs, so i can see the benefits.
If i come over as bigheaded it's not how i mean to be or how i am. I use a lot of water by most standards, you use hardly any.You use ingenuity to invent and perfect things, i wait for alex to nick and perfect the idea and then buy it off him- sometimes i do buy two.
