Undercoating oil

To undercoat?, i know there is a forum on here to undercoat or not.i am a firm believer in undercoating my vehicles especially in Canada. I undercoat my vehicles twice a year,wax them twice a year cause unfortunately they sit out outside. I been looking at fluid film for an undercoating oil, but i got talking to someone and they said they disagree cause the salt and stuff can lay on top of it and stick to it. I regularly wash my vehicles also once a week usually and that’s why my 2000 and 2005 vehicles look great still. I also was told through grape vine an old trick back in the day was to use chainsaw oil mixed with hydraulic fluid?. I will be using a hoist apply the oil. Just trying to do my research on best oil to use and what not. Thank you

There's a thorough response to a similar thread just over the last few days.

I personally used fluid film this year. It caked up with some dirt but I figure that washes off and I’ll apply it again next winter.

 

just go with fluid film

 

Fluid film. I use it every fall before winter. Three spray can for hard to reach areas. Ad gallon can to brush on the stuff on big frame parts. Do not spray on a windy day. Don’t ask me how I know. Keeps my 2008 from Nashville looking like new underneath after five Minnesota winters. Peace. D

 

Another vote for Fluid Film.

 

New Hampshire Oil Black. To hold back the rust, since Pennsylvania used 821,000 thousand tons of salt/brine on the roads in 2021. You gotta use something.

 

Another product similar to Fluid Film but supposedly slightly better is PB Blast Surface Shield. I've used both.

 

I used pb blaster surface shield on a jeep wrangler and it worked great

 

I used Wool Wax for the first time this past fall. So far, I am impressed. Good adhesion and it flows well when first applied. I use my hitch as the best indicator. By now, with Krown or Rust Check I’d be touching it up. No need with Wool Wax. It is still fully coated.

I predict I’ll only need to touch up the truck next year, not a full spray, but I’ll make that call in September.

 

Thank you guys, i have a gallon of black fluid film with a new undercoating gun i plan to use on the frame and under carriage, i will use clear fluid film in doors and under hood areas so it doesn’t stand out like a sore thumb.

 

FYI fluid film smells pretty bad for a few days after application.

 

Try to keep it off of rubber components as you go. I completely remove the spare to get all up in the cavity. Some disposable drop cloth or cardboard and gloves are a must too. Be safe!

 

Not sure your location but:

Edmonton, and Ontario are two locations. Ive oil undercoated for decades. I,believe this guy is better.

he removes wheel,well,liners (you will be shocked at how much dust/dirt accumulates and hold moisture) and more important he dry ice blasts the undercarriage before coating with wax.

i,drove 1200km to,have it done. Good for 3-15 years

 

I use POR15. I drove from CA to WA and back, zero rust. I even got stuck in a mud salt bed, I still have zero rust.

 

Which color undercoating you'll choose and why?
