I will experiment with both the silicone lubricant and graphite to see if either give longer term results. It is tempting to replace the mast however my concern is that the new one will soon develop the wind drag induced slight bend. I would hate to think what must happen to the mast when travelling at 200+ km/h. The slight bend contributes to the mast sticking as rotating it into different positions can help prevent it sticking.

Thanks for your replies,
Greg
