Frame Rust Prevention??

[Magnetic_Drey]

I was at a Toyota dealership today and noticed that 2019 4Runners has some of the frame holes covered up. I immediately checked a used 2016 4runner on the lot as well as my 2017, and the holes are exposed. I’m thinking of buying those rubber tape and cover mine.

I used this stuff. Green color so I could see where it came out. I don't care if it looks funny because rust is less funny.
