How to Deal with Car Rust by Yourself?

[VanLillian]

After grinding the rusted spots, you can see that the rust has corroded the steel plate and created pits. If left untreated, it will rust through and become irreparable. It is recommended to first apply car wax to see if it can remove the rust; if not, try polishing. As long as the rust is not coming from inside, it can generally be eliminated. Use a brush to apply the treatment liquid to the rusted area. You will notice that the yellow rust spots react and turn black, while the rest of the area remains unchanged. The liquid is transparent. Zinc paste is suitable for filling large holes. Cut the zinc paste to roughly match the size and shape of the hole, then attach it to the hole. The edges of the paste should be lower than the surrounding metal parts.
