Geeze no one is jumping down anyone's throat.
You all can't tell me that the same conversation would be said around a campfire with a group of friends about any/all subjects.
And I'll add that my Tahoe that WAS driven in the winters of Wisconsin and the under carriage usually was never washed off consistently. I just got it out of storage up north and brought down here to Florida.
No white stuff remains are visable from the salt just the damage. Second trip to the store it started leaking gas from a rear line. I pulled into a repair shop to see if they would fix it.
First thing the guy said as he looked at my 'Wisconsin' plates was: "nope I don't have time for that today, without even looking I KNOW those Wisconsin fuel lines are 'all' corroded under there and it's gonna take more than an hour to repair that cause it isn't going to be that just one section fix"!. :B
