Excessive Brake squeal

Hi everyone, I was wondering if anyone has had any issues with excessive brake squeal. When i’m on the brakes in normal city driving, they will sometimes begin to squeal. It is a little odd however because they will only squeal if on the brakes at a certain amount of pedal. In other words, if they start to squeal if i brake a little more or less than the current point it will stop squealing. This also only happens after the brakes warm from city driving. My car is a CPO 2018 XE S (380 hp) and purchased with only 1000 miles. My current service advisor thinks it may have something to do with the fact the car sat for over a year outside. The car was at a dealer in the los angeles area for a year before i purchased, and was also outside and close to the fires in the los angeles, CA area last year. They have checked the brakes multiple times and nothing is inoperable.

I've had this problem since I purchased the car. That 60-0 is to remove glazing on the pads, which does make some sense, but I've had the squealing come back during spirited driving where I'm putting a lot of heat into them. It's really annoying to have an expensive sports sedan squealing like a race car when I pull up to a stop.

Hard stops to remove the glaze from the brake pads even taking the pads out and roughing them up by rubbing them on a concrete floor helped a bit, but the squeak/squeal soon came back.
Then I found this magic cure: https://www.ebay.com/itm/CRC-05080-D...AAAOSweP9eTOdW
Completely banished the noise forever!

I think I have removed most of the glaze with those hard stops, but just like yours it does come back when driving more quickly. I also thought that maybe it is because I live in a hot climate, meaning brakes work harder? Temperatures right now are often over 90 and have seen 110 fahrenheit.
