Yeah I guess they're cheaper than I thought! Wonder if it's worth it out here, or if it's really just not an issue in CO. They use mag chloride on the roads out here, but not sure if that's close enough to salt to really be an issue. Although maybe at 24 years old, that matters little with regards to rust...Bluetooth borescopes are pretty cheap on Amazon, I'm planning on getting one sooner or later
Also was looking at one of there for keeping the frame's innards sparkly

That would be really nice! Probably works a lot better than just spraying directly in from the few holes on the side of the frame.
