FK1000p for me. Great bird and bug resistance. Easy on and off. Lasts all winter in the Midwest. And one tin lasts for years. It is, however, a SOB to get out of pads.
I will make up a strong bucket mix of warm water (not at the point of being hot but close, basically as hot as you thing the adhesive on the pad will tolerate) with a pretty good amount of Megs Super Degreaser (Super Clean may also work) and will dunk the applicator/pad in and squeeze and release several times while in the solution. Wear gloves or your hand will be so dry they crack. After that, I will let soak in the solution until the water goes back to room temperature. Generally the time frame while I am cleaning up/putting stuff away from the detail. When cool, dump out that solution and run the applicator/pad under hot water while squeezing and releasing several times. This will remove most of the FK1000p. Toss the applicator/pad in the wash machine. Set on small load, add an ounce or two of Rags to Rich and quite a bit more Super Degreaser and set the temperature to high, assuming your machine is not so high that the adhesive will give out, then use warm instead. This will create a ton of foam, do not use a level higher than small load or may foam out of your machine. At this point, FK1000P will be out of the applicator/pad but all will have a strong odor of Super Clean. So next I would prep my normal wash for all the other microfiber towels and such used in the detail and toss the Super Degreaser smelling applicators/pads in that wash too and the smell will be gone.
Sometimes you will need to do this process with the towels you buffed the FK1000P. So far the heat has never ruined a towel fortunately.
