KUDOS Rick! This was a great comparison, even with the limitations you had. It's great to see some actual pics, so it's really valuable even as is!
I just discovered that FRESH 303 will attract SOME dust.....I was being sweet to my honey and after he washed his Polaris RAZR, I started 303ing it...black plastic fender cladding, black side panels, black hood, front light surrounds that are black plastic. Only got to do driver's fenders/side as it got too stinkin' hot........he went on a ride about 2 hrs later, came back pretty dusty only on the driver's side starting from the rear of the front tire wheel well back, (just as Rick pointed out too....so are you going to redo it using horizontal stripes??). Wiped off easily with Calif car duster, not sticky or oily. So the parts that get more blowing air, or don't get sprayed from the tire dirt, don't collect much dust.

Part 2 -Did the passenger side, waited 2 days, then went on a ride...much much less dust sticking, absolutely just like it would've been w/o any 303.

TEACHABLE MOMENTs: I just had to use this silly phrase!
My impressions:

1) Don't go anywhere dusty for 2 days after applying 303...i.e. let it dry for a while. I'm beginning to think that's why directions EMPHASIZE to wipe/rub it down DRY immediately.....which of course, I didn't follow to the letter...I wiped it on, and wiped it several more times, still with the damp 303 rag.....looked fine to me

2) Applying 303 to rubber appears to be entirely different than applying to plastic. The rubber areas on my roof rack have been thru lots of rain, and they're still darker than pre-303, doesn't appear to have washed off as easily as Rick experienced. Likely that 303 absorbs into rubber much more so than plastic.

3) The black/dark charcoal gray plastic components of my roof rack where I applied it over 2 months ago, thru several rain storms, still appear to be "treated", a little less than when I 1st applied it, but not back to original state. So it appears it can be more durable in some materials.

4) I'm really thinking there's a "drying" or "curing" time that's beneficial to 303 being more long lasting.

5) I've done my entire interior panels, dash, console, door panels, etc...over 3 months ago (actually before I went to Moab), still looks great, no abnormal dust collection.

6) Ashley I think that's why your cladding DOES look a tad darker, from your use of the B2B. Looks great!

So just like Rick said, which product is best depends on your circumstances.

Can't wait to hear more info/details/impressions of the TS-1.
