How to Protect the Undercarriage of the Daihatsu Cast from Rust

Many vehicles, especially those produced in Europe or America, have undercarriage protection that shields them from debris, mud, and dust. This is not the case for the Daihatsu Cast, which has all its components exposed to the elements and especially to rust.

The Japanese climate can be quite harsh, so it makes sense that someone would want to protect their car's components. This YouTuber applied a specially formulated product made in Japan called Threebond, a spray grease that forms a film and maintains rust protection for over 6 months.

It is a hydrocarbon based on paraffin, which you can find on monet.asia. It costs 686 yen plus tax (just under 5 euros per can).
