Has anyone any experience of Kingfisher maisonary paint or weatherflex??

Some manufactures make 10 or 15 year life claims on the tins but Kingfisher
make no such claims, I am interested in them as they are local to me and I
like to support local business when I can.

The only claim they make is that it protects the historic Tarbat Ness light
house in North East Scotland

Thanks
