Well......I have two Gotham version twos...........they serve me well.......and cost a bundle..........they will make your pants leg move, and will lift a heavy Persian rug off the floor.........
I live in Dallas, and Phoenix..........all my AGM batteries lasted twice as long as flooded........in those two environments.........absolutely fantastic service life..................
ReelX by the CorrosionX people down in Texas.............you will never beat it with anything........(and as a bonus, your internals will NEVER corrode........) !!!!!!!!!!!!!!!!
i use about three drops of corrosion-x HD on every single lug before tightening ........... 20 years and no problems.......and never a galled nut...............(I do use a calibrated torque wrench though)............
I use mine with the Yubikey......Lastpass works really well with it.......just don't see how anyone can get around yubikey encryption........love love love it.............
longer than the engine lasts, if using top quality oils, filters, and changing them per the book......................this assumes you are not starting it up at 40 below and going immediately to full throttle......or something like that..............
FWIW i have ordered dozens of RP oil filters off amazon......for at least five years........(or at least as long as they have been making them)........ and have never had rust or corrosion issues..........i'm amazon prime and usually get them the next day shipping free.......but ...........i am...
