Wrong way to look at it. The hose should be replaced every 10-15 years no matter what, as the hose itself can fail instead of the fittings. No real need to do fluid film or similar, they'll just need replaced again in 10-15 years given same environment.

Just try to get some of these hoses when the vehicle gets old. I'm specifically referring to transmission lines.
