Fluid Film11.75 Oz Undercoating Protection Aerosol Spray Can Black 6 Pack, Rust Inhibitor and Prevention, Anti Corrosion and Lubricant, Spray Can Extension Wand

I undercoated a new 2018 Ram 3500 with this stuff used not quite a gallon on the whole thing. Really like it, it does not have the negatives of other products. If you get it on the paint, Just wipe it off. It does not compromise electrical connections, so you can spray without worry there. Holds up well. What I really like about it is that it can be power washed off...it’s not a coating that’s hard to remove if you need to. But it’s sticky which is what you want, and clings depriving oxygen. Of course you need to reapply every several years, although the successive applications are really just touch ups. No real smell as others have stated, it won’t bother you. I applied to the driveshaft and missed a spot. Two years later I can easily see where it protected, and I wish I did not miss those spots! It creeps which is very important. You want it to get into tight spaces. Very liquid during application then seems to gel later. Likely the best anti corrosion you can get. In my opinion, it’s the most forgiving product you can use: power wash the underside of your vehicle, get most of the dirt off, hose the underside down with Fluid Film, don’t pick and choose where you spray it just cover everything, keep off exhaust, otherwise just hose it down. If any lands on the paint, just polish it off. The amber product does a great job on the front of big trucks keeping bugs from sticking. Just apply like a wax, leave a slight film...you won’t see it, bugs won’t stick. You can thank me later.

This product works great for spraying the frames on cars and trucks.

Fluid Film Black has solved my corrosion bad dreams and nightmares. I'm that guy that wants my stuff to last forever and am willing to clean, buff, wax and elbow grease as much as needed to get there. It was always a matter of time before rust eventually gained the upper hand, but not since Fluid Film Black entered my solvent arsenal. Spray it on, be diligent and consistent and it will reward you will dull black over everything metal you care about. Even items already corroded can be saved. I am hard to please, but this product blows my mind. Buy it for yourself and for anyone who cares about their equipment. You will not be disappointed. 10 stars if I could give that many!!!

Arrived no leaks and packaged well unlike if you order the gallon which will show up leaking everywhere

Wheeeeeeew this stuff is stinky and unbelievably messy. If you get it on a cement floor good luck. Try lysol and a deck brush with hot water and get to work. The stuff reeks for a couple days and then suddenly doesn't stink anymore. Time will tell how good it is, but it applied well. Do NOT apply indoors

Got a new Tundra and fluid black was my first application. A lil messy so wear old clothes and a hat. I used 4 cans but could have got by with 3 just doing the frame and rear-end. The 6 can is the best value.

Used before reapplying every couple of years, l live in the north with a lot of snow and salt. This undercoating is great for keeping metal and frame parts like new.

First off, Fluid Film is great! But I was happy to pay the higher price just to get the wand, to find out it is complete garbage. It doesn't fit the can properly so it is oozing all over your hand the whole time wasting the Fluid Film. Do not pay the high price just to get the wand. Fluid Film is sold in many Big Box stores for about $10/can no need to buy here for a wand that is terrible!
