Undercoating this weekend; What to spray?

Wojciech Gierczynski said:

Been using Fluid Film for years. Just buy yourself 5-6 cans (no need for fancy sprayers etc.) Lay under the truck (dirty job but well worth it) and go to town. Only thing is to try to avoid any rubber hoses. If you spray on it it wont fall off but jsu try to avoid it. I spray Fluid Film before every winter. Actually 5-6 cans was first time coverage ... after that its only touch up before every winter in high impact areas where water washes off Fluid Film.

Switch to Woolwax and you won’t have that wash off problem. I recommend buying either the Woolwax or Fluid Film Professional Applicator Kit. You absolutely need the 360 degree spray wand to get inside all the frame pockets and crannies on these things. There’s no way to protect it otherwise.

You can buy attachment that you put on regular Fluid Film can. Its around 16" long and it sprays 360°. Been using regular cans for past 5 years on my previous trucks. One before my Roush Raptor it was 2017 Roush Supercharged F150 and I had it thru 3 Chicago winters parked outside. Not a spackle of rust when I traded in for my Raptor. With that being said no need for sprayers. Couple regular cans of Fluid Film will do same job, just little bit more flexing you have to do with just a cans. Just a word of advice ... if you want to spray Fluid Film underneath your truck on the driveway or inside garage, lay some plastic first (even the cheap one that you use to cover furniture while painting) otherwise you will have Ice Skating Ring imside your garage or on the driveway.

I can promise you from many years of experience that an aerosol can cannot provide the same level of coverage and product travel, especially on a fully boxed frame, that a proper setup ran off 100 lbs. of air pressure can. 3 years of Chicago winters are not a good metric for determining wether or not your anti-corrosion treatment work. Most trucks will look perfectly fine after 3 years wether you treat them or not.

Depending on the manufacturer, between 6-9 years is when you will start noticing problems if the vehicle was left untreated. With the amount of pockets, channels, and cutouts that are in the frame and cab of these trucks, if you are not getting a wand in every one of them with some good pressure behind it so the product can travel, you are wasting your time.

Any idea if it will work with the Amsoil product as well?

Not sure if it will work with the Amsoil stuff, if it hardens up it will clog.

I swear by using boiled linseed oil. My 2002 ford ranger and my buddy’s 2005 ford ranger and also my wife’s old 2003 ford taurus are proof. All 3 of them were bought brand new and oiled with it since new and they have withstood western pa winters since new and are in excellent condition still.

Done it same way on my Expedition for 10 years before ... frame did not have rust. You can get thru openings in the frame perfectly fine with just a Spraycan and attachment. Yes you can tell after 3 winters in Chicago if you doing good job protecting it or not. They put so much harsh chemicals on the roads here like never before. I can tell after my wifes Lexus which I didnt do underneath but I wash undercarriage and its parked inside. Its 2017 and after 3 winters whatever is exposed underneath has coat of rust.

Reading all this makes me really glad I live in Texas!

any idea which product would work best just to protect the shock bodies and some of the more visible suspension components from some occasional salt and snow exposure. I make it up to the snow (Lake Tahoe) about 6-10 times a season and want to protect some of the parts from looking faded/corroded around the suspension from the salt.

I made the mistake of not immediately spraying down my last truck with full KING suspension and it looked like crap after one season. All of the aluminum and fittings looked corroded and aged after one season of snow/salt and maybe even only 5-6 trips to snow at that. Looking to prevent this on the Raptor if at all possible.

I sprayed Nyalic in the wheels wells of a Tacoma with excellent results.
