In France we seldom use road salt, especially in the west of the country where I live but my W124 comes from belgium and I have a rusty jacking point and rust in one wheel arch to fix which is a classic on older Mercedes. Other than that, the car is solid, I had a good poke around with a screwdriver and I can only find surface rust underneath the car. I'd like to keep it from rusting even more by spraying something oily and I'd like to avoid anything rubbery that can trap moisture if cut/hit by rocks.
Here are the (cheap) options I found so far:
- WD40 : seems way too thin, I think it would evaporate in hours.
- New motor oil : still too thin to cling for a long term, bad for motorbikes if it drips all over the road.
- Used motor oil : same problems, even worse for my health and the environment but free.
- Chainsaw oil : seems like the best option, would definitely cling. A bit too thick to seep in every crevices. What about mixing it with something like mineral spirit or kerosene to spray it? If the lighter components evaporate while leaving the thick oil everywhere, this would be a nice and cheap solution. Seems to work as well as Fluid Film or Krown for many people.
I don't want to spent too much money on other products as I like to tinker and try and I'm cheap. I don't mind if it's a tacky mess under my car, I hate rust.
