My cladding was pretty faded and required contant Mother's BTB applications.

I would say it restores your cladding to the same darkness as new. The key is going very little bits at a time and letting it "soak" into the cladding. It took me nearly 2 hours to put mine on I went so slowly and put two coats. The first coat I went around piece by piece with a saturated rag and really rubbed it in.

I also washed mine VERY thoroughly before hand and took windex to some of the parts of cladding where I new that things like armor-all or eagle products had slung from my tires.

I THINK the consensus about KATs (correct me if I'm wrong KAT) was that she either had some type of application before she owned it that was blocking the RR from penetrating the ABS very well or there was some type of residue she couldn't get completely off in her initial prep.

KAT also had the unfortunate experience of being the first to find out that if it chips at all, power washing is a bad, bad thing.
