Rust-inhibiting products in Taiwan?

I’m planning to get students to test the effectiveness of DIY rust treatment recipe(s) as part of a “scientific writing” course.
Probably use steel washers as the target, if I can find plain unplated ones.

It would be nice to compare with a commercial product. I’ve used Waxoyl in the UK, which I didn’t think much of, and I understand the US market leader is called Fluid Film, and may be similar.

Is anything comparable available in Taiwan?
