I used FX-100 for the first time the other day and we have sick pollen here in NEPA/SENY.
After a usual day at work the car is just covered and it looks to be a different color.
The FX-100 really minimized the pollen. It now certainly picks up pollen but the amount is about half of what it was and it looks like only the bigger "chunks" of pollen stick to the car. The finer pollen/dust is really minimized. The glass was much cleaner for the drive home as well. It usually looks greenish/yellow from the pollen.
The next day I QD'd with 425 and had the exact same pollen reaction today after a day at work. Only bigger pieces of pollen stuck and less of the fine stuff. So far I'm sold on the static minimization.
I only air dry my MF's, maybe that is helping me.
Today I just tried 146 so we'll see what happens with that one tomorrow.
I agree with the 425 streaking issue a bit. It does seem tough to keep it from streaking and my car is titanium grey. I only QD in the garage after it cools down. I don't have any streaking issues with 146.
Lastly, the 425 does attract bugs of all sorts. Drives me up the wall.
Overall, I find 146 to be the big winner so far. More cleaning capability, easier use and the surface is just about as slick as the 425. We'll how it does with the pollen tomorrow.
