Rust speckling on paint
Railroad dust? I have 2011 Yukon that looks like that, and I don't live/work anywhere near a railroad. It might be stuff in the paint, or like 3 spots I have rust coming THROUGH the paint (lower panels behind the back doors, and on back quarters where body meets fascia). -
Paint Bubbles / Blisters then rust
No Ospho. I figured the POR15 would stop it since the surface appeared to be ok after light sanding. I'll add it to the list for the next go around. So I guess on the wheel well rust I need to get behind there and might as well remove the sound material and see. I seem to remember the... -
Paint Bubbles / Blisters then rust
This was repainted last summer/fall. (and sadly my clear coat overspray is peeling). Other side is completely fine. In fact, other than these two spots, there's no body rust at all (except for lower edge of the liftgate) This was also redone (and I removed the fasica) as well (this one... -
Paint Bubbles / Blisters then rust
Back Passenger side, behind rear wheel where the fender meets the plastic Fascia. This one here I treated the metal with POR-15 which is a moisture cured urethane which should stop any wicking through. Driver's side panel bottom behind the driver's side rear (LH Rear) door in front of the... -
Paint Bubbles / Blisters then rust

The truth about Led Hid lights and bad kits.
Yes. I put Vanquish LEDs in my 2011 Yukon night and day difference...pun intended. Much brighter and not get flashed. They are working great in the stock housings. -
fuel trims
Single digit LTFT trims I wouldn't worry about. That's pretty normal, sometimes can even depend on weather and fuel used. Usually on the 3800s (Did a fair bit of tuning on those myself..johnh on clubgp.. 04 GTP, XP Cam, TOGS etc.) closer trims kept the WOT fueling inline, as well as having a...- johnh

Speaker Replacement Question, 2011 Yukon XL Denali with Bose...
Thanks Everyone that's what I was looking for. Sounds like (pun intended) that the Infinity Kappas are a good replacement. Now I just need to convince the wife to wait a bit so its not cold and snowy outside to do this (I do have a garage, but its unheated), or find a good installer who won't...- johnh

Speaker Replacement Question, 2011 Yukon XL Denali with Bose...
One (both?) of my front door speakers seems to be blown. My wife (while getting a windshield chip fixed) asked the place about replacement speakers (we have Nav and stock HU). They told her that with the Bose system you needed to use "only factory replacements". This seems like nonsense to...- johnh
