I am gathering all bolt rust proofing methods, if you know of any, please share!
So, since I am living in a country with lots of anow and salt, rust has always been an issue for me. I started researching how to rustproof the bolts, because there is nothing worse than a rust-welded grade 10.9 bolt that had its head snapped lol.
All steel bolt rust proofing methods I've seen are based on creating a layer between the steel and oxygen. But the way the layer is made varies wildly:
- Oxide based coat
- Carbon based coat
- Metal based coat
- Oil based coat
- Paint based coat
For example there is a technique that is called "Oil Burn" where you get the bolt red hot and dip it into motor oil. There are various issues with this technique, which I will explain in a later post.
With your suggestions I will make a spreadsheet with various pros and cons listed and will share with the community.
As to prove I am serious about this, here are my current experiments: Before:
