Fluid Film 11.75 oz. Spray 2-pak

excelent product

Smells bad and works excellent.

I began using Fluid Film as protection for my vehicles several years ago. I live in Ohio and road salt and other chemicals are used heavily in the winter, and they eat away at bolts, brackets, suspension components, and body parts. Cars that are generally mechanically able to go much longer, face an early death due to rust from underneath. Each fall I buy one can per car I want to treat. If you have a large vehicle and/or want to be extremely thorough, you'll probably want two cans. Do this as close to the first snow fall as you can handle without freezing your fingers off. :) First, make sure your undercarriage is clean. Take it through a car wash with underbody spray, or hose it off at home, the day before you treat it. Then what I do is.... open each door. Insert the straw into each drain hole found at the bottom of the door. Give it a small spray with straw pointing forward, then a small spray with straw pointing rearwards. Repeat for each drain hole, in each door. This will protect it from the inside. Next I climb under the car. I use ramps for being quick, but jackstands would be fine. The most important things to cover, if you are only going to use one can, is every SEAM where body panels meet, the rocker area, and every nut/bolt/screw. If you have a used car and it already has rust underneath, you can tell what is most susceptible. Just saturate it. Do not spray your brake rotors, although frankly it would just burn up and not likely to cause long term problems. If you have steel brake lines and/or fuel lines, coating them is a good idea. With two cans, you can give a light coat to the entire underside if you desire. Preferably, I would do this before you park the car for the night, so the film can set up well, rather than immediately taking the car for a highway drive where perhaps some would drip off. Also, I'd probably leave it outside for a couple hours before pulling it into the garage, due to potential for a few minor drips. Most of it clings though! I have an 8 year old vehicle that I've owned since new, and giving it one good FF application each November has given me a car with no body rust and very minimal surface rust underneath. Most of it will hang on for a long time and protect you for most of the winter. If you're a true die hard, then washing your undercarriage and repeating the application 1/2 way through winter would probably be ideal. The extra cost and effort and cold isn't worth it to me.

Great deal on an indispensable product: the only lube standing up to well below freezing. Also a rust inhibitor so snow dwellers should give it a try! It lubricates in hot weather just as well.

This is another no brainer product to prevent rust under your car or in the engine compartment. It works quite well. It's a bit pricy but worth the cost. I'll be buying again.
