I have a wooden garden seat with cast iron ends. The ends have been painted many times, but are now in a sorry state. The best approach would be to strip all the paint off and start again.
(This brought back memories of when ah were a lad, when we would tek us cast iron bits to t' foundry, slip t'foreman 'alf a crown, and he would dunk t'bits into summat, and they would emerge as bright as a new pin).
In the absence of a local foundry, any ideas for stripping off the paint? Nitromors? Something else?
