Additives and Dyes

[TehYoyo]

Hey all. I'm looking around for some gold fluid additive and found two questions:

First, how does Mayhem's Aurora Gold fluid additive work? It says that the "pearls might get stuck"...does that mean there's an actual reflective, solid thing floating around? Will that damage my system?

I also found Primochill's Gold Dye Bomb. How vivid is this gold? Is it pretty nice? It also warns that it will stain your loop if you use it....I'm fine with stained tubing - that's easy to replace and easy to fix. But will it have a negative effect on the performance of my components?

Thanks for the help.
