We took in a Grandpa fresh Toyota Tacoma as a trade-in. The rear differential was so rusted out that it was leaking. Literally oozing out of the axle housing. I drained the oil, cleaned up the diff, knocked off as much rust as I could and sprayed it with brake clean. Then generously applied Flex Seal. Did it work? #TACOMA #flexseal #fixedisfixed #rusty #oilleak
