Undercoating Complete! NHOU Permanent Boss Wax System Applied. Work done by Mass Mobile Undercoating in Holden, MA

I wanted to share here as I looked for people’s input and advice before I got our 2026 4Runner undercoated.

After calling a lot of local shops and gathering information I decided to go with Mass Mobile undercoating in Holden, MA. The owner Todd has been great to work with and took the time to explain everything and provide clear up front pricing.

I went with the Boss Wax system from NHOU which is a permanent dry to touch wax on outer frame parts that stays flexible and oil fogging on all inner frame and body panel surfaces. Todd also does annual oil undercoating with NHOU product as well.

Looking forward to keeping this thing rust free and bringing it back to Todd at Mass Mobile undercoating for fogging and wax check in 2 years to see how it’s holding up!

Never heard of this stuff. Looks good though. I just usually grab a couple cans of Woolwax and go to town.

Cost estimates?

Looks good. I've never heard of the stuff either but it's probably Dinitrol 4941, like mine. My undercoater called it their "Citadel" line or something like that

It’s the Boss Wax system from the brand: NHOU. The initial work was $1400 and the guy who owns the shop will do refogging (oil mist spray) on all internal frame and body panel areas and wax touch up as needed every 2 years for free or he said $50 if it is a lot of wax touch up.

I get a yearly undercoating with the NHOU lanolin product (forget what it's called). $230
Works great.
$1400 seems super high for undercoating.
