    Just bought a used sierra 2500HD the whole thing is pretty clean except for a few spots here and there that show some minor rust.

    First Question- Should i take a wire brush to those rusty areas then spray with FF or can i apply FF to it without scraping?

    Second Question- I wont be salting with this truck but after each storm i will be washing the underside of the truck with a weak stream of water, or should i not even bother to hit an area that has been FF'ed?

    Third Question-When I undercoat should i avoid certain areas on the truck such as exhaust system, and near the engine block, or is it ok to spray those areas?

    Final Question- When I apply FF how long will it last, days, weeks, months? I will be doing it with either the undercoating kit or spray cans if it matters?

    Thanks guys, and Dano if you see this post your stuff is wicked pissa.

    I'm interested in the answers to these questons as well. I can tell you that it should last for 4-6 months in winter depending on your road conditions/driving habits.(I've been told) I don't think you have to avoid any areas but I'm new to the product.

    If is is only a surface rust, you can just apply Fluid Film right over the rust. Fluid Film will stop rust on contact. Any rust bubbles or flaking rust needs to be removed. Otherwise Fluid Film will penetrate these areas and when the rust exfoliates (falls off) you will be left with bare untreated metal.

    Second Question- I wont be salting with this truck but after each storm i will be washing the underside of the truck with a weak stream of water, or should i not even bother to hit an area that has been FF'ed?
    A light rinse is fine. Fluid Film is very thick and will not wash off easily.

    Third Question-When I undercoat should i avoid certain areas on the truck such as exhaust system, and near the engine block, or is it ok to spray those areas?
    Fluid Film will just burn off when applied to the very hot areas.

    Final Question- When I apply FF how long will it last, days, weeks, months? I will be doing it with either the undercoating kit or spray cans if it matters?
    Using the "bulk" (gallons or pails) Fluid Film would be a better choice. The bulk product applies at a much thicker viscosity. One annual application should get you through the season.

    What are your thoughts on the undercarriage wash used in truck stop washes? I don't think that is very high pressure. I recently bought a new truck and as we all do want to keep it as rust free as possible, so I just ordered a FF kit and will apply it next week. Wondering if I should continue to have the undercarriage done at the truck stop or not.

    I've attached a brochure of what they have at the truck stop.

    Thanks

    I use Salt-Away and it works very well. It says that it doesn't leave streaks or residue, so I just spray everything with that and let it drip dry. Touch up as needed with FF.

    I`m addicted to the hand car wash (preasure wash) in the winter months. I have one down the road a few miles. If roads are clear enough for me to make it home without trashing the wash job, I will go everynight. Will I be washing off the ff in the wheel wells and leaf spring areas or will it hang in there?
