Undercoating / Rust proofing

Been doing a ton of research here and still coming up 50/50 on the go or no go on this....Just got a new truck and debating on the ziebart vs oil spraying...my truck will spend most time outside and will be driven on the barren salt tundra that will become our highways. Any opinions for those in the north country?

 

krown.com if you can get it there

 

i would love to but im down in south pennsylvania, im thinking a good thick thick coat of paint may be best then add some oil/wax protectant - has this worked good for anyone in particular?

 

Oil, I do mine every fall and all my friends... IT WORKS! Will do yours if you don't mind drivin north an hour? PM me if your interested.

 

Spray the undercarriage with oil. Works for our tractors quite well on the farm. It's a messy job but just gotta be careful and you'll be good to go.

 

I'm about to spray Fluid Film under mine.

 

ziebart is not very good imo

 

what kind of oil?

 

agree with this FF is the way to go., I started a post on this same subject ! look for it and you can see why FF it better the rubber undercoating

here it is

 

I'm in the middle of doing this, just taking a break for some TW.

Fluid film seems to be a great product. Professional plowers and farmers swear by it.

I bought 4 cans and just used up 1 and it covered way more than I thought it would.

 

I think that Ziebart is the best choice for an undercoating.

 

Oh man that stuff is nasty.

Ive worked on plenty of vehicles with that on and trying to get tools over bolts and things off is crazy. then once you get the parts apart it's all rust under the zeibart. If there is a crack in the undercoating then stuff gets in and won't let it out.
If it's worked for you then my all means stick to it.

 

So what do you use, how do you apply it, and whats the prep process for the oil?

 

I use used oil from semi's and spray it with a garden sprayer. If your truck is really muddy I'd recommend pressure washing it a day or so ahead of time.

 

Illegal in most states and used oil has a lot of nasty stuff in it. FF did mine in the fall still is wet and on the frame not a bit of it has washed off.

 

Cheap and effective way right here.

Theres no need of doing it now, so wait til fall. When youre changing your oil, keep it! Use it on your truck! Make sure its dry outside and drive down a dirt road after you spray it. This will work.

 

Krown is the best for sure, but any undercoating is going to help you v.s. a salty highway. Do it annually to keep the protectant working, as it gets washed off over time.

Krown is hands down, the best out there if you have one in your area. Their product will creep up panels, and into seams. It's pretty cool stuff.

 

This^^^^though it does get a little messy! It doesn't have to go on so thick it drips, but enough that every thing is coated.

 

I agree! Fluid Film works great...I like the fact you can still see the frame and the nuts and bolts aren't covered up like they would be with rubberized undercoating.
