Saw some of the posts here about Fluid Film and bought a spray can to try on my hydralic cylinders to reduce possible rust. I had been using WD 40. Based on the praise of the stuff here on TBN I thought I had better try it. I sprayed it on my backhoe cylinders since it is currently off the tractor and I want to reduce chance of rust. I went back to the backhoe after a couple of weeks and the cylinders were pretty covered with flying bugs, gnat like. They must have liked the stuff.
I'd be careful of using WD40.
On my pickup cap I used it to clean and lube the pneumatic spring loaded piston things that keep the rear door up.
It seemed that the seals used on the lifters were allergic to something in the WD40 and within days the rear door stopped working.
Must depend on the type of seals used, ie rubber, vitron butyl etc.
