I'm looking for some valuable information/experience on how to avoid corrossion.
The bike is a CB1100EX from 2015. Past owners lived close to Normandy beaches. I just have very few areas where I see some corrosion. Otherwise, everything else is "nickel-chrome" like a french would say.
As you seen in the picture, most of the corrosion starts at welded joints. I plan to use ACF50 after reading some of the posts here and there.
How can i safely remove the existing rust ?
Does this mean a poor weld quality from Honda ?
Thanks,

I don't think the cause is a bad quality weld. From the pictures, it looks like galvanic corrosion to me.
When you have two dissimilar metals, if there is no electrical isolation between them, one will rust while the other is "protected".

Can't help on how to remove the rust. Sorry.
On the fuel cap/tank interface, I guess you can try to isolate one part from the other. When you have stainless, high nickel alloy, or chrome against any other metal... the other metal very likely going to rust.
