Rust Never Sleeps

[Mark Jennings]

So in 2017 we had the tub down to bare metal….inspected everything and cut out the bad, welded in good metal….and wouldn’t you know it, 7 years later, rust bubbling through…

Looks like I’ll be cutting, welding and painting…..again….Arrrrgh

2017, no indication of rust just under the rear of drivers door.

2024, it’s bubbling through.

Dealing with the same stuff here. Every spring I find more when I wash the winter grime off.

My classic trucks stay off the road in the winter, the salt solution the highway dept. uses is slow death for them.

Nice looking 40 Mark. At least that's an easy patch if you decide to tackle it.

That's why I paint mine with a rattle can.

We’ll get it cleaned up, patched and repainted…..I guess after 56 years of road use, a little touch of ‘skin cancer’ is to be expected.

Just a reminder to all…..,no mater how much work you put into these old girls, there will always be more work on the horizon.

I think part of the problem is parts are taken to bare metal and examined. Bad spots are identified and then parts are primed, believing that it protects the metal. Unfortunately, regular primer does not keep moisture from getting to the metal unless epoxy primer is used. While taking care of fixing problem areas moisture is passing through the regular primer and starting the rust cycle all over again. Epoxy primer will actually seal the metal preventing moisture from getting to it.

Epoxy primer and polyurethane was used, I think this is a double walled panel, moisture between the panels and after 50 plus years….it made it to the surface.

I’ve done some research on sheet steel used in car bodies from the late 60s through the 80s, e.g. pre-galvanized bodies. A good portion of steel production was from recycled sources. Basically, it was non-homogenous…meaning a lot of different steels were used, melted down and rolled into steel sheets….this was more true in Japan and Europe where steel was a scarce commodity after WWII….and non-homogenous steels have a tendency to self rust…..any moisture, dissimilar metal and you have an electrolytic cell…add some salt or sulfur to the mix (a better electrolyte) and it accelerates the reaction.

It just the nature of the beast….rust never sleeps.

That is a common area for rust. My untouched 75 has a small rust spot around that location too. I think it might be because there is a small piece of reinforcement metal tacked on the backside. Thru the yrs I've noticed a lot of rust happens where 2 layers are over lapping.

Neil Young and his band Crazy Horse nailed it alright. "It's better to burn out than it is to rust." Here, on the Texas coast, you can watch things rust before your eyes.

Same here on the west coast, I live near the water and loved it when I was a Surfer. When I stopped Surfing over 10 year ago I tried to move but the Wife said NO WAY
So I just keep fighting RUST

That a sweet looking 40 and Shop !

Epoxy primered, after cut and patch in 2017.

I can't complain, I drive it to enjoy it, year round.

Needle size holes is hard to see when welding patch , the weld need to be seal on the back side or you get bubble soon after the painting is done
Too much grinding on the weld also make some thin weak spot that rust quickly

I pondered this very situation and my answer to slow the rust as much as possible was to galvanize the tub than epoxy prime and paint

Noted…..but I’ll do my best….and slow it down, and hopefully the NEXT generation of Land Cruiser owners can fix the next bubble(s) that pop through. Most of us here on Mud have done our job, preserving what we can….so the next generation can continue this effort and keep these girls alive to see another day.

Hot dip galvanizing is as close to rust proof as you can get for steel; seriously thinking of having my frame done. OTOH; I love my Aqualu tub.

Mark,

What’s that foam pad on your main steering rod for? A grip for micro-adjustments of toe-in? FFF.

Awesome Question….it’s actually aluminum round stock, bored to fit over the tie rod….there a couple of set screws on the back side to lock it in place. I would like to tell you it is my iteration of a Racing Tie Rod Airflow Stability Enhancer…..but it actually hides a boo boo. When I set the initial tow, I used a 10” Pipe Wrench and this covers up the Pipe Wrench Jaw Marks left in my nicely straightened and powder coated tie rod

Nice attention to detail

Could also double as blinker fluid storage, but TRD RTRASE has a nice ring (Racing Tie Rod Airflow Stability Enhancer) soon everyone will want one!
