>A few years back now Toyota had a big recall

Mustie1, absolute YT gem of a human being, did a couple videos showing his efforts to salvage post recall Toyotas. Recall was a scam. Instead of replacing bad frame, or stripping, cleaning and repainting Toyota opted to pay third party contractor to just spray some black goo on frame rails so they last 12 more months while the goo hides corrosion (and traps more moisture speeding up the process).

TLDR involved welding plates to replace eaten metal and regularly coating in oil/liquid film protection every year.

Interesting. It was my understanding that the official Toyota procedure involved lifting the cab and bed off the existing frame and transplanting all of the rest of the truck to a new frame.

This seems to outline the requirements: https://static.nhtsa.gov/odi/tsbs/2019/MC-10154787-9999.pdf

The warranty work is listed at about 40 hours of duration for frame replacement, which seems rather short to me. For about a million potentially affected vehicles that's not a cheap recall.

Maybe thats what they were supposed to do, but the post recall trucks Mustie1 worked on all looked the same - spray of hard coat over the corrosion/holes the size of a fist.
