Fixing Micra K11 part 2 - rustproofing sills and rear chassis rails

In this video I cut in to the sills and rear chassis rails of my 1998 K11 Micra. After vacuuming them, I spray a good amount of cavity wax to slow down the rust... Also did some painting of my previous welding job. So far I have used for this car: ~ 3 cans of CRC Galvacolor RAL9006 silver ~ 2 cans of Biltema solvent free cavity wax 36-2429 ~ 1 bottle of CRC Rust Remover
