Av8paul on the hamb, is taking his roadster body off the frame to clean it.after driving to the salt lake. And driving on the salt lake. He just could not get the salt out and it was causing rust
The other day we had a heatwave, 29F, so I took my shitbox escort to the car wash. As I was spraying it off a wad of ice fell off with a piece of the body imbeded in it. There is no way to keep a car clean enough so it will not rust where I live. On an up note my county has used up its yearly alotment of salt so they are now just spreading sand. Accident count has already risen.
Salt isn't the only ruster. It's an electrolyte that speeds up the process but the oxygen molecule that bonds to the iron to make rust can come from water or air. hardly at all just from air... The reason rust spreads like cancer is that the rust contains extra oxygen which migrates to other iron atoms. humidity will rot a clean car anywhere bare metal is exposed. oiling one down even just a little is the best prevention if it doesn't have a perfect and perfectly maintained paintjob. fisheyes in paint are from silicon. I bought an f600 in denver and when I went out to pick it up i drove my pickup out, bought a tow Dolley at American tow Dolley in fort Morgan and dollied my pickup back home to omaha. the f600 had been sitting awhile and I put a quart of marvells mystery oil in the gas tank (it's not a diesel). the f600 didn't burn any oil but boy you should have seen the water bead in the rain on my pickup after having a few hundred miles of f600 mystery exhaust blowing on it.
We have LOTS of salt on the roads here in SW Ont. Oil spraying is popular. I spray my DD each year and it's holding up quite well (2000 Buick). I often thought it would be cool to find a rust free Arizona car from the 60's (say a 63 Biscayne more door), strip it, POR (paint over rust) the floors and frame/inside of the doors, rear 1/4's and trunk etc. I'd replace the brake and fuel lines with stainless. I'd pull the glass and treat the channels with POR as well. I'd run stainless exhaust and hangars. Fresh paint, a good coat of wax, spray the undercarriage again with Fluid Film (fantastic for preventing rust) for extra insurance and drive the car all year round. She'd last 20 years! A lot of folks even oil spray their old cars prior to storage. BTW-here's the link to fluid film. CLICK HERE Todd
