Also be careful of what kind of silicone you use. Liquid Wrench as a product they call silicone, but it seams to be a different mixture. My dad used it on his Trooper, and got ugly black streaks on his paint (over spray, it was windy). I used CRC brand and had no problem. (And mine is WHITE!) I'm guessing his was more of a combo silicone and penetrating oil type of deal. Not trying to tout any brand here, just personal experience.
So true, "silicone spray" is not the same from brand to brand.
For years now on my cars and bicycles, when I top off the tires I spray a drop or two of silicone into the schrader valves before I put the air hose on it, to lubricate the valve seals so I've been through a few brands over the years. I also periodically spray all the rubber suspension bushings to keep them from drying and cracking, that can take up to a whole can itself, which I usually finish off by spraying the radiator and heater hoses under the hood.
A little cheap PM that can save a bundle if it makes the parts last much longer.
It might be noted (on the topic) you may not need to remove the door panels to spray silicone on the regulators, a good flashlight and the little red tube thing and careful aim should get you by going through the top. Be a good idea to cover the door in and out and maybe flush the paint with water after to be safe.
The door panels are not hard to get off but it is unecessarily tedious and if you don't have the right tool it's easy to bust off all those damn trim clips.
For years I've been using one of these:

modified by grinding a much bigger relief hole where the nail slot is, probably about 5/16", to better fit around the clip. Works fantastic.
If you take the door panels off make sure the plastic sheeting is in good shape when you reassemble it.
If you take ALL the panels off it's a good idea to rotate the door pull brackets from front to rear. That's the little black plastic piece attached to the door. They crack over time and wear cycles, the rears get little use and they are hard to find.
FInally check the sash clips on any power window issue, they do break and will cause other issues to become worse. For instance it will destroy the regulator in short time. They're cheap (generic ones available in the cheap red "help" parts packageded at all auto parts stores, the ones I got were 4 in a pack for $12, 2 fit my vehicle) tho you do need to pull out the window to get the goo from the old one off.
