Best option for spraying applying fluid film?

I purchased a 2015 Tacoma from a guy who kept it in a state that had no salt. I however live in North East Ohio and we get both salt and brine placed on the road in winter. I had Toyota do the free courtesy corrosion prevention treatment to the frame but to be honest that treatment didn't look like it covered all that much so I thought it would be a smart idea to apply a product like fluid film to my truck before winter. At first I just thought I'd purchase a couple of the spray cans of fluid film but I'm thinking those cans might not give me the full coverage I'd really be looking for. So now I'm looking at purchasing a gallon of Fluid Film and trying to figure out my best option for applying it. I hear an airless paint sprayer works well but I'm not sure that would get inside small tight area as well and a spray gun that can accept a hose attachment. Here is what I'm thinking might work best:

Spray Gun:

$110 woolwax Pro Undercoating Gun by Kellsport

Compressor: Fluid Film:

I plan to apply fluid film annually and this would cost around $300 this first year, a little more than I was expecting but as long as the spray gun/compressor hold up all I'll need to buy is more fluid film each year... Anyway before I pull the trigger on this I was hoping to get a few opinions from the Tacoma community on this.

Do you think buying Fluid Film in its bulk form and spraying with your own equipment is the way to go?

If so, do you think I am choosing the correct spray gun/compressor to get the job done?

Thanks in advance for your time/opinions on this subject.

 

Check this site. You can buy a gun with accessories and fluid film/wool wax kits.
You’ll just need a compressor. Small pancake is fine.

This kit from the site you linked looks interesting: https://www.kellsportproducts.com/W...g-kit-1-ONE-Gallon-Kit-with-PRO-GUN_p_45.html

It has the same spray gun I was thinking of purchasing from Amazon and comes with a gallon of woolwax + a few nice extras. Is woolwax any different from fluid film?

 

From what I understand it just thicker. It will hold up better to road wash.
That’s the same place I originally bought my fluid film products. Also told that woolwax doesn’t stink as much as fluid film.
There’s a couple guys local to me that have spray meets $40 a truck and they sprays everything.

I think I will go for that Woolwax kit but I'm not sure a small compressor will really do... I do have little husky air scout compressor, its only 1HP and has 1.5 Gallon tank. Do you really think it can handle the job?

 

Why not try it first and see. It might be fine.

 

That a fair point. Thanks.

 

There website recommends 70-90 psi ideally 3 gal compressor.
@jpereira2 can you comment on this

 

I got the Kellsport gun listed above. I used Woolwax with this Porter-Cable compressor:

It worked well for me. Woolwax is pretty thick. Do it in September when it is still warmish. I even put quart bottles filled with Woolwax in warm water so it would flow better. Alas, I waited until October when it was a little chilly. Hope to get to it sooner this year.

 

So last summer I sprayed my truck down with approx 9 cans of fluid film , Ive checked on it when I’ve been under the truck and it’s held up great so far . I can’t see needing only a can or 2 to cover up some road wash areas. My point being you might not need to apply as much as you think the year after . I’m in eastern pa and we got nasty salt and brine here.

 

Interesting, I think I will also do my wifes van to though.

 

Just a reminder.... Tacoma members receive a discount, free shipping, and no sales tax outside of MA on all Woolwax® products. Just enter promo code "tacoma" at checkout.
Let me know if I can provide any additional information.

 

What type of compressor is needed to apply Woolwax®? How much psi?

Woolwax® undercoating guns do not require much pressure. 70 – 90 psi is usually adequate. Sometimes the extension wands require a bit more pressure if it is cold out. Even small compressors generally operate at about 125 psi. More important is the tank size. If the tank is very small, you will be constantly waiting for the compressor to recover. Generally speaking, any compressor with a tank 3 gallons and larger will work fine. If the compressor is adequate for spray painting, it will work fine for vehicle undercoating.

We strongly recommend putting an inexpensive regulator on the gun end. That way you can leave your compressor alone and let it run at it's normal psi (125-150). It is a lot easier to regulate and tweak the psi right from the gun. It's a standard 1/4" fitting on the Woolwax® guns. These regulators are $10-$12 at Harbor Freight, Home Depot, etc.

 

Nice, the discount really made purchasing the Woolwax kit a slam dunk. Thanks for sharing.

 

I use a 6 gal porter cable pancake compressor and it’s plenty. It’s not like your spraying non stop, your doing quick burst and then repositioning. Crank it up to 80 psi. and have at it. Lower the spare and get in there good.

 

I don't have access to a vehicle lift and I have used both methods, compressor, and aerosol cans. And without a lift, I find the spray cans easier use.

 

I pay a guy 100 a year to do it he jacks the truck up high and gets everything. I then go through it on my own throughout the year and hit any spots I see Starting.

I can’t believe how much these rust quickly.

 

A lot of people do their vehicles with spray cans. It's a bit more expensive because 1/3 of the can is propellant. But the Woolwax® aerosol formulation is the exact same as the bulk (gallons, pails), so once all the gas escapes you are left with the same thick coating.

 

It's frame metal material choice.
If you can remember the first unibodies that came out in the 1960s, they also rusted out like crazy. We bought a used Rambler unibody and I drove it until the rear springs separated from the body. If I remember right the car was about 8 or 9 years old when I had it taken to the scrap yard.
Then auto manufactures started treating the lower unibody with better rust preventive coatings. I remember seeing new car brochures showing, like, a multiple-step rust preventive treatments that included galvanizing and zinc-rich primers on the lower sections of the unibody. Since a frame is a major safety component of some SUVs and Pick-ups, may-be that is how they should be treated, like a modern-day unibody.

 

Whats your guys preference between Woolwax and Fluid Flim? I have used FF since I can find the aerosol cans locally and I like it. But I don't have any experience with Wollwax. Going off the description between the two websites they seem very compatible or similar.
