A friend offered to undercoat my GF's & my cars yesterday at his home shop, so we spent the day at their house drinking, and being merry.

I asked him last minute if he could help me change my ATF filter and do a fluid change, so that's also up-to-date. Easy to get the pan off with me prying down on the exhaust with a long pry-bar while he pulled the pan out.

The fluid was old, but not burned up, and the magnet has zero chunks. He said it all looked really good overall. We drained the fluid w/an evacuator, refilled, and drove on the highway twice to cycle 4 gallons of fresh ATF (Valvoline maxLife synthetic) through the valvebody, coolers, and torque converter. Although not a true flush, the fluid now looks fresh and clean.

Her car is still amazingly clean underneath, and a unibody (VW Tiguan) so it was easy/quick to spray. We just had to undo a few plastic underbody covers, and zip-zap, done.

Mine was a little more involved. And took 2x as long. I sprayed the heck out of the undercarriage, but the frame coating has been sloughing off since I bought the truck, so he had to alternate blasting the metal surfaces with compressed air, then undercoating, then going back over everything as the metal soaked the Fluid Film dry.

$300 for both cars (and my ATF service) so I'm happy. Best part was he spent over an hour removing the 3M adhesive tape, and buffing out the front of my hood where the old bug-guard has scratched the bejesus out of the clear coat, for free.

Replaced the lugnuts on the Yukon. I had swapped the OE wheels a while back with some newer wheels and didn’t have capped lugnuts. Decided before winter gets here, I should get capped ones in there. Went with these…..

Neighbor is a mechanic and has lift at parents farm, so i took Yukon to him for some undercoating.
He did an amazing job, car is sprayed all out, from every single corner inside-out.

While there he noticed one fuel tank strap was gone.

Got the straps yesterday and went down low to see where did the old strap go, you can see on the picture it decided to part ways peacefully.
Anyway, jacked the tank back up and put the strap back on.

I’m surprised it was driving like this since i got it and me nor anyone else ever noticed.
I wonder if this also cures my issue with not being able to fill full tank LOL, since it was hanging sideways :D

Keep an eye on those lugs - I have the spline lugs too and they have rusted to hell and back...I am on the hunt for black chrome lugs now.

We’ll see how they handle an Iowa winter.

I've had a set of black spline lugnuts for a few months now, and they are already getting rusty. I'm going to have to repaint them when I switch over to my winter wheels/tires.

(It was 70 here in NH yesterday, and I was sweating in a Tshirt/pants. It might never snow here. )

I am so frustrated with them - switched out wifey's winter wheel/tires today and 2 of the capped acorn lug nuts popped off...ARRGGHH....Gonna be looking for solid chrome lugs for her Equinox.

I will either find Black Chrome or settle for solid chrome (hate that idea)

BTW, finally installed the Husky Mud Guard on the ol' HOE...They dont look too bad and thanks to @Charlie207 , I knew that I needed to get creative with the mis-aligned screw hole...Did all 4 corners in about 1.5 hrs....
