These examples seemed to be in California, but I'm particularly curious about how Cybertrucks in snow-prone areas that heavily salt roads during the winter will fare.

What's wild to me is that a lot of modern cars don't rust as much. Some weird black magic coatings on the undercarriages now, 'cus shit used to rust so fast decades ago. They still rust, just not as bad it seems. From the article though this seems way more basic than the super-caustic-road-salt rust though.

  I’m shocked at how good car paint has become. Paint on many 20+ year old cars kept outside looks new. Meanwhile you’re supposed to paint metal roofs every 5-10 years. Granted, roofs are painted in less ideal conditions and eventually it’s paint on paint on paint, but even still the difference is striking.

    Once in a while they fuck up the formulation and it leads to massive recalls. GM tried to do something to their primer in the very late 80's, I believe it was meant to improve corrosion resistance. But the unintended consequence was that the paint didn't stick to it properly, and cars parked in the hot sun just started to peel after five or six years.

      Sure and matte finish is inherently problematic etc, but the point is we have the technology. I’m sure it’s not cost effective for roofs etc, but even still it’s pretty damn impressive.

    > Meanwhile you’re supposed to paint metal roofs every 5-10 years. What the what now? We've had the same roof sheets on for 30 years, no paint, no rust, corrosion, degradation at all. Ditto for the sheet metal fencing. Colorbond roofing sheets display exceptional durability. They are engineered to resist severe weather conditions such as extreme heat, heavy rain, and high winds. Thanks to its exceptional resistance to corrosion, a Colorbond roof can last for decades with minimal maintenance. https://www.metalroofingonline.com.au/products/roofing-iron/colorbond https://www.metalroofingonline.com.au/products/roofing-iron/... Painting the roof and fences isn't on the list, and we're pretty proactive on maintainance - we've just flushed out all the grey water and rain water pipes about the place to remove silt and other buildups.

      The factory coating on Colorbond roofs lasts a long time, but you can’t apply that coating a second time. Paint it and you should stick to a 5-10 year cycle or accept a shorter overall roof lifespan. With cars you can get them repainted and still expect that kind of lifespan on the custom paint job. If you want longevity without the hassle copper roofs can last 200 years without painting, just at a much higher initial cost and fixed color.

        It's summer now in Australia, with 40 and 45 degree Celsius days. In 18 months (not this winter, the next), the plan is to strip the tin off altogether, replace part of the evaporative cooler that's rusted out a bit, slide in a few extra steel trusses, and then retin the roof with extra insulation to increase the R value, redo the solar hot water placement, and cover the rest with state of the art 2025 solar panels. That should avoid having to paint for another 30 years and give us an excuse to host the kids, grandkids, and cousins for a week - everybody loves a b̶a̶r̶n̶ ̶r̶a̶i̶s̶i̶n̶g̶ roofing party.

  If you want to make it last forever, jack it up, clean, and spray a lanolin oil coating once a year.
