Would recommend this

Put this stuff on my Toyota box frame because they are notorous for rust. I applied it last fall and its been on for a year. Applying it is difficult if you dont have a sprayer, I used a paintbrash and a had my vehicle jacked up on solid cinderblocks, not easy and time consuming but it works and will get you a good undercoat for $55 all in (including the $10 paintbrush). Its a great value, especially compared to buying aerosol cans of fluid film. Anothor plus of the fluid film is that it doesnt smell bad, doesnt smell great but it as bad as brakleen. I hardly went through any of the bucket when I did my undercoat, Ill probably get 5 years out of it. Over the winter I drove through rain, snow, and salt. There isnt many/any signs of rust. The only negative I can say is that this stuff will attract road grime if you do a heavy application, this wont road grime wont lead to rust but any time you touch the frame youll get road grime on you. The application is very resilient, I see people saying it will wear off with just rain. This is absolutely false, even on my vehicle driven at highway speeds in the wet this stuff didnt wash away. You would need something like a pressure washer for it to remove a coat.

I wanted to undercoat my 2019 Toyota 4runner, knew about the product, just wasnt sure how much work it be. With the right gun I spent $89.95 for kellersport gun, it went on really easily, took about an hour. Just used cardboard underneath, make sure you buy a mask/respirator. The mask/respirator was like $30, well worth it, as I use it for several tasks. Yes it does stink but the smell goes away in a few days. It does really stick to the frame. I was so impressed went ahead and undercoated my 1997 T100 for kicks.

Easy to apply with spray kit

I use this on my plow and bobcat bucket in the winter to prevent snow from sticking. It works decent for that. Both are painted (not rusty) and both sit out in the cold. Stays put for one snow removal, I must apply every time its gonna snow. I use a chip brush and it applies quickly. Tried to use this under my mower deck to prevent grass from sticking, it just wears off immediately and then grass sticks, so didnt help for that.

I have used it for 4 years now since I moved to this rust belt state. It has really saved my vehicles from rust. Works great.

Seems to work well . Will know more next year. When I see how it holds up.

I’m a first time user and it was real easy to apply to the inner frame of my vehicle. I will reserve judgment on rating it for longevity and value for a few years.

This product is needed to preserve your car if you live in an area that uses salt on their roads in the winter. Im a firm believer that this product is the best on the market

I have a 2017 f150 with not even I hint of rust.If you live in the north east and are one of those guys that keeps your vehicle till the wheels fall off this stuff is a must.every truck I have owed was still running great but had to junk because it rusted to crap.brake lines rot,spring shackles rot etc and it not fun working on a rusted truck.Every September I spend a few hours and spray the truck “buy the spray kit it’s worth every penny” September is good because you still have some hot days where this stuff can seep into all the joints.It really sticks to everything and will still be there from the year before but it will wash off inside the fender wells.I usually buy a few spray cans so in the winter I can touch up spots that get washed off in the fenders.I learned about this stuff from a friend that has a fleet of vehicles and has been using for year and his trucks don’t rust.
