I had to make a couple of passes with a green scotch pad on the back of the neck of my CP Thornton after Sunday's service. I can almost see Chuck cringe over that!!
The reason: My sitting position in the musician's area is in a corner opposite the drummer's cage and not much air is moving around that spot, causing me playing problems!
My first reaction was how difficult is was for me to comfortably play a bass with uncoated flats on it. With the generated hand sweat and not enough moving air around me, the strings became sticky and very restrictive.
My second issue was the constant attempts to reseal the custom mold IEM's during a song. Very annoying when they are needed to hear and then they become unsealed when I move my head!
So, I replaced the uncoated flats and went with DR Pure Blues Nickel RW on the CP Thornton, which was much better strings wise, but my clammy hands made the nitro coating on the back of the neck feel a little tacky. A couple of light passes up and down the back of the neck with the green scotch pad solved the problem. I also bought a small fan to keep the air moving around me.
Last night's rehearsal was a breeze with the bass and the fan.

Very satisfied with the results!
As for the IEM issue, I bought a set of Comply Soft Wraps. They wrap around the outside of the tip of ear canal piece on each the IEM. It's a thin strip of self-adhesive memory foam that you compress between your thumb and index finger just before inserting. The IEM's stay sealed until I remove them and they are comfortable to wear. Far, far less expensive than trying to get new molds done and purchase new IEM with hope that they stay sealed per design.
Very happy with the Soft Wraps and I've been using the first pair (5 pair per package) since 8/27 (6 uses) and they are still in good shape.
