Fluid film is very cost effective if you understand its performance.
Amsoil metal protector vs fluid film.
Lasts a year or more i haven t had to re treat an area i ve sprayed it on.
Fluid film will certainly help under mower decks if proper steps are taken.
Oil that s too thin for its application won t form a durable fluid film on metal components.
Little too pricey for my personal use.
Always used the amsoil hdmp in the past.
I ve used the amsoil metal protector at work love it lasts long smells great.
At home i use crc sp 400.
The oil film protects the bearings from wear helps keep the piston from scuffing against the cylinder wall protects the transmission gears guards against compensator wear and more.
It s some great stuff that goes on liquid and within a day is a waxy coating.
Ready to spray the underside of my wifes wrangler rubicon before winter.
Fluid film or amsoil mp heavy duty metal protector for underbody.
