Fluid Film 11.75 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.

My family spends a lot of time on the Gulf Coast beach and my vehicle undercarriage was beginning to show signs of rust and corrosion. This was easy to apply but wear old clothes. I like the black color for two reasons - one is that you can easily see if you missed covering an area and two, it just looks good. I feel much better about using the truck on the beach now for many years.Also, one of my spray cans didn't spray. I contacted the company and they're sending me another can, no questions asked. Very pleased with the product and company.

Great value, works great and easy application! I it can be messy but it works!!!!

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!!!

Good stuff worked well for my silverado

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.

I did the inside and outside of my frame on my 2018 f150. The included hose adapter is not too good but better than nothing I guess. I had to get one more can for the inside of frame so 7 cans total. I've taken it through the car wash a few times and only a little bit has come off. Smells really bad and takes a few days to go away

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!
