found a rust-proof zinc-based, and made produce color as the originals.
Unfortunately you can see the brush strokes, but the danger of rust is removed, and even scratching the paint.
without haste, and with the invaluable support of Adri75 the work goes forward.
replaced chainrings, fork, brakes and levers, shifters and complete wheels ..... work will continue, as seatpost, stem and handlebars will be also replaced.
Really looking forward to seeing this finished - I always liked the fact that the designer/s seemed to think hard about where to braze on the cable guides on these frames.
