After one of my earlier videos in this mini-series Gordon Tate, a viewer of this channel, offered me to trial a product he has developed. 'Tate's #1' is a molybdenum plating solution which can be used to restore rusted ferrous items by neutralising the corrosion sites thus reducing the likelihood of further rusting. The plating also improves the appearance of the item.
As recommended I trialled this product on some old rusty tools and conduct a simple experiment on pre-rusted mild steel samples.
The results are favourable. I conclude the video with 6 points I have learnt about corrosion prevention from this video and the previous video, part 3.
