    I had a 2007 Colorado, the body rusted, but the frame....man that frame.

    A frosty looking flat chassis black paint, never rusted.

    Sold truck to friend, just turned over 250k still no rust on the frame, nor the brake lines (must have painted them afterwards)

    I re-did a truck once, sandblasted, and painted with the "Now illegal" Zinc Chromate chassis black. Waste of money.

    If I ever do another frame off deal I am having the chassis hot dip galvanized.

    My year 2000 Land-rover was just beginning to show a little rust on the chassis where moisture gets trapped by the diesel tank - not too serious and eminently repairable. But as I want to keep it ANOTHER 20 years I had it re built on a brand new galvanised chassis. It should out last me !

    Oh come on now.

    You can get stainless brake calipers, brake line, hardware, et all.

    Press brake up what you want, put a spool of Stainless wire in the MIG
    and have at it.

    This Colorado we have behind the shop didn't fair so well.

    Why don't people oil spray their $40 000 trucks, it only cost $100 a year and it makes a huge difference.

    Just don't use used motor oil from gasoline engines. It can be corrosive. I have also seen it deteriorate rubber components.
    Back in PA we used to oil everything. We could get pretty much unlimited used diesel oil. I kept all the plow trucks oiled up really well.
    It worked pretty darn good. Far better than rubberized undercoating!

    Yup, I would love to know what the frame of mine has on it.

    Did they farm out the frames to overseas ? Maybe some paint that is not
    allowed over here ?

    The issue with the '14-18' models seems to be the adhesion of the the wax/rubber coating to the frames...................the steel wasn't prepped correctly.

    Why aren't they made from electrogalvanized stock, the same way that cars are?

    $. And the truck makers count on buyers getting a new one after five years, enough do to make the cheapo construction viable.

    GM forgot they went bankrupt 10 years ago and are doing their best to do it again. GM makes the WORST cars on the road today... Kia and Hyundai make WAY better cars. It is shockingly bad.

    I believe many truck frames are "hot stamped", meaning the blank is heated before stamping. The galvanizing would never survive.

    You've worked on Chryslers right? I was just riding in my sister-in-law's Chrysler minivan. I think it's a year old. All the weather stipping for the sliding doors is already falling off. The rear AC doesn't work. She's already threatening to trade it.

    I'm going to have to agree with that statement. New GM stuff is cheap, plastic, garbage. You might as well buy a Barbie Jeep!
    Yea, they are all bad (as Wes points out). But, GM is real bad. New vehicles from especially the big three are virtually designed to be disposable.
    I'll give credit where it is due: the LS is a bad-ass engine. GM did an amazing job on that platform. But, everything else they do is cheap-cheap-cheap junk.

    My sister-in-law has a Chrysler mini-van. They love it. It's probably two years old now. No issues whatsoever.
    BUT: the issues are coming. I can not convince them that 20k is not an acceptable oil-change interval! LOL

    Had two '89 Blazers got 12 good years out of them. I currently have a 2000 AWD Astro with 216,000 on the clock rust is finally showing up. The '03 Tahoe I have on the other hand has rust popping up everywhere, bottom of doors top of fenders, wheel wells. Brake lines rotted out a couple of years ago. I figure the fuel lines will go any day now. Never had a car that the ground straps even rotted. Garbage Motors in my book. I too get as many years out of a vehicle as I can.

    That might work in some climates, but not here. It would take the average person 2 years to put on 20K miles. That's a shit ton of hot and cold cycles!

    Oh well, timing chains are so easy on a minivan...
