Waited for nice calm cooler weather today for doing my 5-10 minute yearly rp-342 cosmoline touchups on the tacoma, while inspecting the entire chassis. Been a little over 5 years now in one of the saltiest states with this undercoating, and gotta say all still looks showroom under there. Fall cry from the hours spent applying this stinky fluid film crap I use to use on my tundra twice a year, yet I still had areas everywhere of surface rust forming at this time. All I can say is this cosmoline stuff is the bomb.
