Application: I used a spray bottle, and worked it in with a terry towel. Some guys like to go straight from the bottle to terry, its all up to you.
Viscosity: Hard to describe. Kind of like cooking oil, if you shake it it bubbles within it.
Usage: I've tried tires, hard plastic trim, rubber trim, wheel wells, etc. It works best on textured plastic, but it does a pretty good job on rubber trim. I don't use it on tires, cause it slings. Looks great though, not worth the mess IMHO. Maybe for a show car, that's going to sit for a coupla days.
Durability: It doesn't run if you let it set up for a couple days. If water gets on before it can "soak in", it'll run. I figure that "soaking in" is just a laymans term for the solvents evaporating, but maybe one of the guys with a background in chemistry would know better than me.
Shine: Under no circumstances would I use this on the interior. It really is an "extreme shine" product, and it would make the dash look absolutely terrible, IMHO. If you REALLY like the armor-all look, however, you might want to try it.
Durability: Why do I think it'd last a coupla months? Cause Trim Restore does

I wouldn't say trying to troll Poorboy's as much as just expose the truth. All the evidence that I have seen points to PB's private labeling a good portion, if not all of their products from CG's. If you have some evidence that points otherwise, I'd like to hear it. And no, I don't consider what they say on DC evidence

. I understand that Steve has a business to protect, and I don't blame him.
I guess the short and narrow of it is that I'm sick of hearing the "don't trash PB's, unless you have proof" argument. Having personally seen a number of PB's (and Adam's) products used up against CG products, the only better proof that I could personally see would be a shipping label from CG's warehouse to Steve.
