Just to add to this thread
We had John come back last week and paint all our ironwork in gloss black , looks brand new now and while he was here got a price for our ballustrades (which are a pain to paint as some go over the pool and there are plants on the other side)
He came yesterday and did them all then inside and outside the perimiter wall and even the side of the villa above the tiling (he is amazingly fast and VERY accurate) and said any problems, to ring him and he'd come back and sort them (there are none)
