My 1st post will be kinda long. Okay, so I just bought a 2001 LX470 with 120k miles. I found it in Atlanta, GA. Never seen snow, salt, off-road use, or towing. Interior is fantastic, but the really amazing part is the undercarriage. It looks showroom new under there--barely any dust. I work on all my cars and I did not want a heavily rusted truck to work on. No rust or corrosion anywhere--I was shocked. I couldn't find anything like this in Ohio.
I felt kind of guilty bringing this cream puff back up to the salt belt, so I wanted to find a way to protect the undercarriage. I read a lot of the threads where folks spray oil on the undercarriage of Jeeps and the various environmental objections about it--so I found something that might please some folks.
I decided to spray a thin film of silicone oil on the undercarriage. Silicone oil is not hygroscopic. It's also non-toxic and you can buy food grade quality oil which is used to lubricate machinery that processes food. So I bought a 2.5 gallon Haynes silicone oil (FDA approved). Any drops that fall onto the ground are safe and I do not need to worry about contaminating the water supply, etc.
I then drove the truck up on some ramps. I first tried to spray this stuff through a garden sprayer and it was too viscous and just drooled out. I then tried my HVLP air gun which can spray laytex--bingo! I could spray a fine aerosol. I put on an N95 respirator and some eye protection and then proceeded to crawl beneath the truck and sprayed everything and tried to avoid exhaust components. Much to my surprise, I was able to coat the entire undercarriage with ~2 cups (1 pint) of oil. So there you have it, there is my version of a simple way to prevent corrosion on the undercarriage.
Now I have to replace my AHC fluid and accumulators. The truck rides really harsh.
I just bled my brakes using a compressed air powered Mityvac and was thrilled with how quick it went. I recommend this to everyone versus pumping a brake pedal.
This is a great site!
