did you spray it or paint it?
that hammerite was jolly good stuff, covers rust really well..
reminded me, got things in garden ought to do summat with (out of sight out of mind)
one is flowerpot holder, one of those wire things you put on wall... welll rusting where the plastic has cracked away
I found a little plastic pudding basin and use it for water for the birds, just hangs from tree.. the basin didn't quite fit, a little small so bound the loop with twine to reduce the hole a bit, perfect!
also thing blacksmith made does need hammeriting.. came oiled but of course that wears away and is just mild steel, sort of curly S shape and hung crystals from it decorative. but the rust has gone down onto those, they need a scrub and the whole thing sealing, get round to it one day eh?
