Undercarriage coating/spray recommendations for 2016 Tundra

Was thinking bout getting undercarriage treated to prevent rust. Got a quote for Milspray for $189 & it’s recommended to be done annually. What you guys been using? Truck is in NJ and has moderate winters some some salt used on the roads.

I have a local shop that undercoats with fluid film. I've been getting it every year and not a spec of rust on it.

 

Sweet!! Thanks!! How much they charge?

 

Move to a salt free State.

 

They have different levels of coating, meaning how extensive they get with it. The first year I did a level 3 which is pretty extensive (they drop the spare, remove the taillights, etc) and I want to say it was $250 and then each year after a re-coat has been $150.

 

Fluid film is good stuff.

 

Been using Fluid Film for years, I apply it every fall and have had no issues with rust.

 

I say save your money and buy an under-vehicle power-washer and wash salt off yourself. Then go out and buy the rubberized under coating (the old school stuff) and spend a few days under coating frame.

Project farm did a great test on the different products. I've been using the CRC Marine stuff now because of his video.

Another vote for fluid film here. Easy peasy. It lasts all yr without issue. Reapply every fall

 

I've been thinking of doing this. What shop did you use?

 

Out your way, actually, in Ayer.

New England Rust Prevention.
sean@nerustprevention.com is the owner.

Wasn't the cheapest, but did a great job and dropped the cat protection shields and brackets, coated everything, and reinstalled.

Mention the forum or "the guy with the cat plates and special bolts" to see if he'll toss you a discount.

 

Great, thank you. I'll reach out to him. This is one service I don't want "cheap" anyways. If that makes sense.

 

The fact he removed it all and treated behind it all, then reinstalled and treated them, too, sold me. I'm finding it everywhere, too. Not a complaint, just an observation. Very thorough.

IIRC, you can also check the MA thread. I think someone stated they do it as a side gig, but they were down on the South Shore I believe.

Good luck!

 

3 cans Amsoil HD Metal Protector every Fall.

 

KROWN. 139 bucks and about 45 min. Great stuff.

 

Wifey won't let me

 

x2. Three cans does the trick.

 

For like $40, it’s a no brainer.

 

No.

 

Yup

 

But you don't have any snow then.

 

Does that dry to a hard finish or does it stay tacky?

 

Krown Rust Control applied to an older Tundra.

and a pic of my 4Runner after product was applied.

 

Blaster surface shield is my go to now. No dripping like Krown. And no drifting onto to the paint and windows like Fluid film. Excellent product

 

It dries but stays somewhat flexible. Smells awful while applying but the smell goes away.

 

My wife and I get our trucks treated with Krown each year, drips for about a week then it's good, as long as you don't park on asphalt it will wash away from cement after a few good rain storms.

My brother-in-law just had his tundra coated with NHOil last year and seems happy with it as well.

 

Gotchya! Thanks! So I probably can wait til the fall right? Or get a coat going now? Also….how much should I clean the undercarriage prior to application…..jusy shoot under there w a power washer? Run it thru car wash w undercarriage option? Or jack it up on a lift and power wash it?

 

If you are taking it somewhere they should have a rinse they use that neutralizes the salt and cleans it a bit before they undercoat. Once its coated though you never want to clean the undercarriage since it will take some of the product off and also if high pressure will push water into places it may not be able to get out of so easily resulting in the opposite of what you are trying to prevent.
