Fluid film undercoating

Hi I am looking for more info on fluid film undercoating what do people think of the product my frame is still in good shape am hoping to keep it that way what do you think of product are there any downsides to using fluid film on a truck frame are there better products and what do you think of my trucks frame?

 

Just coat it, you will get alot of opinions on what is best. As long as you steer clear of rubberized undercoats and stick to something oil based you will be good.

 

It works. But its a messy pain in the ass and needs to be applied every year. Your frame looks good. I wouldnt bother , but that is just me.

 

What state are you from

 

New York

 

To bad. As a taco member here is doing wool wax for 100.00 a pop

 

What do you think of fluid film?

 

Its good and works well, but there isn't a consensus on the "best" undercoat on this site, you will get a lot of opinions. Like I said any oil based undercoat will do well, but the "best" one won't be found here.

 

I applied Fluid Film to the frame and misc other parts (trailer hitch, etc) around last fall. I primed and painted all of the welds and crawled under and sprayed everything I could get to. It's a little messy to apply as others said but doesn't really drip unless you overdo it. It's still on the frame and other spots I did but the coating is a little thin in spots now. I really wanted to do the inside of the rear bumper, the front cross piece with the tow hooks on it, and the hitch since they take a beating in the winter. (the inside surface of the bumper was already coated with surface rust) The Fluid Film coating is still shiny and fairly thick on the bumper; all but gone on the hitch and cross piece. I actually like this characteristic. Snow, rain etc slowly wears it away. I'll be doing it again this year. I bought 2 cans and one did almost the entire job. It works. It leaves a residue which gets all over your hands and clothes if you contact it, but it's a minor price to pay IMO.

I'll probably try Wool Wax this year on the front cross piece, hitch, and all of the hitch, frame and bumper mount pieces in the back when I do it again this fall.

 

Wool wax like I had done today but s almost the same as fluid film. Wool wax is just thicker

 

If you live in New York and you want your frame to keep looking like that please use Fluid Film every year. It’s very easy to do, you don’t even need a lift or anything. If you don’t have a compressor or paint gun just use about 6 cans and it should be enough for the frame. They sell a 360 wand attachment that shoots FF out of a can real nice so you can hit the inside of the frame.

 

I've had good luck with FF, started using it on a '98 chevy van and now use it on my Tacoma. I find it to be effective. 2 cans will cover the entire undercarriage but be careful of the exhaust and even more careful around brakes and rotors. In theory FF could ignite on the exhaust so after applying (always get some on the exhaust) I try to do a few short drives to burn it off in a semi controlled way, the smell off the hot exhaust linger for about a week.

Project farm found some worthy alternatives but I've always used FF, I find if you do two spray cans a year (I do one at the beginning of summer and another can in the fall) after about three years you'll have a layer of grime and fluid film that does not wash off at the car wash (I don't mind the grime) and seems to do what it's supposed to.

I recommend it.

 

If you have an air compressor to apply fluid film then ok. I tried fluid film early days into ownership and found that it washes away to easily. That one picture posted does show some rust the proper way would be to wire wheel the rust off and use hand wire brush, Ospho rust neutralizer , Eastwood primer, Eastwood black Chassis paint and then Amsoil heavy duty metal protector. This procedure should be applied x2 i.e. 2 coats of primer letting dry between coats then 2 coats of chassis paint 2 coats etc. I would use Eastwood internal frame protector with the 360 degree spray nozzle attachment.

This is my procedure for frame maintenance its worked for me.The trick to having a solid frame is still build a layer of coatings over the years. I would not just apply fluid film over rust. USN adage ( 7P) Proper Prior Planning Prevents Piss Poor Performance. GL Winter is coming.

 

I personally get mine sprayed with Krown because they have authorized shops that do the spraying(they do a better job than I can). FF and Krown are basically a horse a piece. Both lanolin based undercoatings that need applied once a year before winter. They both work very well. I find after winter is through the coating is a little thin on the cab mounts so I respray those to keep them wet. For the parts that don't get battered with slush (most of underbody and frame) in winter they are all very well coated still.

 

FRAME P0RN!!! IT LOOKS SO...VIRGIN

 

Lol tak1313 I sprayed it with fluid film should post pics of it all shinny now

 

Yeah I'd like to see those pics (after a drive down a dusty road), FF (or any lanolin product) will not make your frame shinny...quite the opposite (says so right on the can), it'll give you that mad max dusty look.

 

More dirty pics!

 

I did get Woolwax last year on my 2015. It’s thick and worked my air compressor. Lots of stopping to let the pressure build back up. Granted it’s not a large compressor. It worked well over the winter. Truck literally smelled like a sheep but hey it’s manly. Fluid film comes in black which has me curious which way to go this year.


Do you guys bother to wash off what’s left of previous years coating or just go right over top?

 

Another option that I've checked in to, and will likely try this winter, is NHOU undercoating. It SUPPOSEDLY works better than Fluid Film, and it's soy based, so perhaps won't have that yummy lanolin smell. Don't know if the truck is going to smell like soy sauce though.
