Painting cast iron
I am planning my winter refurb. I have a Honda 50HP on the RIB.
The steering horn that forms the main steering fulcrum is made of cast metal (iron I think).
I've looked at a few of these and it appears to be a common fault for them to rust badly, mine has!
I made a half hearted attempt at a tidy up by wire brushing then treating with Ku-rust. Access is very poor so this has been fairly unsuccessful. I need to do a better fix.
To that end I have obtained a spare part to prep before fitting. This also needs restoring as the rust has already started.
Has anyone any suggestions on how to paint the cast part to get a finish that will last?
I am less worried about the look because the part is very well hidden.
All ideas welcome
Thanks in advance
