New 2024 Yukon - long term rust prevention and rubber conditioning

torch · Apr 5, 2024

My 2009 Tahoe died of rust here in New England.
I'm just taking delivery of a new 2024 Yukon, and I'm wondering what on the under-body to paint/cover/grease/silicone to minimize repair headaches 10 - 15 years out.
I'm thinking of painting bare metal, steel cooling lines, parts of the exhaust
Spray Silicone on rubber CV bellows, a-arm bushings, .....
lumps of grease on brake bleeders, any nuts that might need to come off in the future, spare tire mechanisms, and slight grease around wheel lugs and hubs.
paint or dielectric grease on exposed ground connections

Just get some fluid film, or woolwax, (both available on Amazon). 1 to 2 gallons will do the whole truck. Buy the professional application gun with different nozzles ans hoses to reach rockers, doors, fenders, etc. Set aside a whole day if this is your first rodeo to scope out the correct access points.

I generally look for weep holes that allow easy passage, or remove body plugs as needed to gain access. If you take your time, warm up the fluid film in a pan on the stove so it's like thin oil, you will get a nice coating on your vehicle and self....

Once coated, you'll want to touch up yearly on areas that have washed off from washing or road spray. BYPASS the automatic washes and undercarriage washes at all costs - they usually spray salt water in areas it would never get to.

There are a lot of good threads here on this, just search some key words. I've done this process for over 10 years on numerous vehicles with excellent success. When I sell them after many miles of midwest driving, they still look almost new and don't have any body or frame rust. Any paint or rubberized coating will give the guise of protection, but ultimately fail and it won't be noticeable at first.

Why would car washes spray salt water anywhere in their process ?

If they are required to recycle a portion of the water used. It's in that. Salt doesn't settle out like sand or other solids. You then get recycled rinse water blown up under your vehicle that most likely has dissolved salt and other corrosive road chemicals in it.

I live in Nova Scotia…. Both of the major dealer groups in Halifax offer a 10-year rustproofing and undercoating product. I had it on my Toyota 4Runner since new… owned the truck for 11 years and just sold it. The buyers were very pleased with the condition of it. Just took delivery of our factory ordered 2024 XL SLT a few weeks ago and had it undercoated and rust proofed with this dealer’s 10-year guaranteed product before I drove it off the lot. No annual touchups needed on the undercarriage.

Worth the $1000 in my opinion and the all black undercoating looks good too. While all the door panels on the Yukon are Aluminium, the undercarriage isn't, and inside the doors would still have components that can corrode.

I'd be curuis what they use. Maybe it's similar to the old zeebart formula that sticks around forever and never really dries out.

I purchased a new vehicle in 1983 that had optional rustproofing applied at the dealership and it came with a "lifetime rust through warranty". I had a spot that rusted through and they denied coverage because "we couldn't get the rustproofing to that spot". So basically, the car was warrantied against rust through, unless it rusted through. All they had to do is claim was they couldn't get to that spot to deny coverage.

Makes sense in my book. Slightly tacky is a good sign for longevity without cracking, etc
