I don't consider the aluminum to corrode anything like iron/steel does. You might get a little under the paint that makes the paint bubble but it wont penetrate through or vanish the way sheet metal rockers do on an older Expy.'....So we're pretty happy with our '04 expo, and looking forward to the next one having aluminum. Tho I am aware the aluminum corrodes too, it doesn't seem nearly as bad.
No, the carpet is in the way. At least for a while.In the northeast, can’t you look through your floorboards to see underneath? Regardless of what you drive?
Yes & no. I do Krown treatment once a year but it washes off with rain and dirt and time. Same with Fluid Film and all the other versions. I've found a thick coating of Fluid Film (lanolin oil) works well on a protected area like the gas fill tube. Ziebart and other more durable coatings can trap the water and corrosive chemicals (salts) under the treatment and create a nursery for corrosion. My buddy in the paint & coatings business says there is no such thing as a coating that prevents corrosion permanently. The corrosion happens at the atomic level where iron atoms form bonds with other atoms (like Oxygen) due to the strong forces that exist at that level for chemical bonds to form. Since the visible body of an Expy (the paint outside) doesn't seem to rust, one has to wonder why Ford doesn't paint the underside in a similar manner? Or maybe cover the entire underside with a plastic shield … or something. Planned obsolescence? Cost controls? Some dealers will sell you an electronic guard the applies a voltage to the body but I don't think theres any evidence that works. Personally I think its useful to flush out the rocker panels and coat the inside with oil at least annually then cover those holes to keep water out, but I wont know for sure until 10 years from now. And that's a lot of work, who wants to do that? I also think its good the keep the vehicle clean everywhere but especially in places you cant see, like underneath. Hard to do though. A great solution to corrosion is to make body parts out of aluminum, but then there are other issues. Pick your poison.This may be a stupid question, but isn't there something you could treat your vehicle with a spray, coat or paint those under carriage parts with to prevent rust?
