Great technical details. Somewhere I vaguely recall reading about a leaching effect...probably something I read here a long time ago, but can't recall who or what exactly.

Wonder if that's why the Showroom New dye seems to be so effective? Maybe it arrests the bloom because it absorbs into the plastic, or perhaps preventing the bloom from leaching out by being a physical barrier to it?

I've been meaning to do an update on my SN thread...but it's been 18 months and mine still looks the same and I've never applied ANY product to it, no B2B, no Tire Shine, no nothing, ever since I dyed it.
I go thru a car wash about 3-4/year, but I don't get any "treatment" applied or trim detailed on the car at all.

When I was doing the polishing, waxing and then buffing with the Griot's products in January, I got some wax splatters on the cladding. I rubbed with a cloth right away, and they just seemed to disappear....no white residue, no change in look of the cladding..... I thought it would maybe make it shine more, but it didn't.
