Chad R Posted March 20, 2020 Share Posted March 20, 2020 I thought I would show some pictures I took at work. It’s a 2010 Jeep Patriot. This is the rear sub frame. Just wondering what others do for rust prevention. I have used a 50/50 mix of diesel fuel and engine oil and I have also used fluid film both seam to work very well, threw the Michigan winter Link to comment Share on other sites More sharing options...
Pete M Posted March 20, 2020 Share Posted March 20, 2020 I use a 50% mix of washing and accepting that anything I use as a winter ride is essentially sacrificial (salt, the potholes, and the horrible drivers are all vying to wreck my ride). Basically nothing I truly care about sees the snow. Just with washing I've seen all of my various rides push past 200k miles with only minor rust compared to others I see.

sinkrun Posted March 20, 2020 Share Posted March 20, 2020 I just did the front and back frames on a patriot they were gone but I only paid 300.00 for it pretty decent otherwise. I can't say how good it is but I used fluidFilm all over in and around the underside and frames. Link to comment Share on other sites More sharing options...
500 MJ Posted March 20, 2020 Share Posted March 20, 2020 Washing is key. Yay Salt. Still amazing seeing that on an 11 year old vehicle! Link to comment Share on other sites More sharing options...
sinkrun Posted March 20, 2020 Share Posted March 20, 2020 From what I have seen they used no rust proof coating at all on these frames only good thing is there cheap on Ebay. Good cars to buy cheap and flip due to the frames there can be had cheap. Link to comment Share on other sites More sharing options...
Dzimm Posted March 20, 2020 Share Posted March 20, 2020 I would agree with the above that a winter driver in the salt is sacrificial, no matter how well you care for it. On the vehicles I care about I put away for the winter. They get cleaned up and painted asap after I get them. Then I just keep an eye out for any sign of rust and get it cleaned up asap.

strictlyxjs Posted March 20, 2020 Share Posted March 20, 2020 Fluid film after every wash during the winter. My mj will literally be soaked in fluid film when its completed. I bought thr $40 gallon can at napa and do it myself with a spray gun. Its cheaper than the spray cans. Link to comment Share on other sites More sharing options...
Chad R Posted March 20, 2020 Author Share Posted March 20, 2020 I agree that putting a vehicle away for the winter is best. If you can’t from what I have seen running threw a car wash once a week works very well as long as it’s not in the teens or lower. But a family friend sprays the under side and inside the rockers and inside the bed sides with diesel fuel and oil and his truck is spotless.

Pete M Posted March 20, 2020 Share Posted March 20, 2020 it also helps to know the vehicle's weak spots too. rockers, doors, frames, bedsides are the MJs. other cars have differeing locations that you want to wash and protect super well. Link to comment Share on other sites More sharing options...
dasbulliwagen Posted March 20, 2020 Share Posted March 20, 2020 I'm working at a GM dealer now. We had a factory rep come in a month ago warning everybody about filling out our multipoint inspections. Evidently a dealer on the coast had a lady come in for her second oil change on a less than 1 year old car, and was warned that the car was unsafe to drive with rusted rotted broken strut towers and leaking brake lines. She started having a fit about it and contacted lawyers because she wasn't warned about any issues at her previous visit. Evidently this lady drove through the ocean sea water on a daily basis out on one of the barrier islands and never rinsed the thing off. Between the ever building salt and continued wetness it ate that car alive. The dealer took a while to find the multipoint inspection and was facing a huge lawsuit for both the dealer and the individual technician, but they finally found it where it had warned the customer of impending issues. The owner said that they never gave her one and was running on the hope the dealer wouldn't find it where she had signed and acknowledged the issue. She was out for a settlement and a new car pretty much, not to mention ruining the life of some lowly tech. Link to comment Share on other sites More sharing options...
Chad R Posted March 20, 2020 Author Share Posted March 20, 2020 Wow!! I would have never thought it would have done it that fast. Glad I live close to Lake Michigan shark and salt free! Link to comment Share on other sites More sharing options...
