External beading rusting through

[gasanstuff]

Hopesomeone can give me a bit of advice, ive had the rear of my house rendered last year and then painted with external paint. We now have thick brown rust marks running down from the beading through the white paint and it looks terrible. My colleague spoke breifly to a plasterer yesterday and he said that he always uses stainless beading on houses near the sea( we're in Barry)
I know that standard beading was used but does this sound right?
Been told the only solution is to hack off and remove beads and replace with stainless, is this correct ir is there another way??

Thanks

Plastic beads are cheaper.
