"THE" cladding cleaning agent?

[Anita]

Please let us know how it holds up to rain/washes since streaking seems to be one of the most frustrating factors to contend with.

Thought I'd toss in a little update on my own cladding saga...

I'm a longtime user of the Meguiar's Endurance and I'm pretty happy with it, but I just tried Mother's Back to Black just in case I may like it more. Well, I do and I don't. The Mothers is not as greasy, but Meguiar's won't look greasy if done right. Application is not as easy as with Meguiar's - you need to use more of it to get an even look, and a dab of Meguiar's certainly goes farther. A bottle of Meguiar's will last WAY longer (I've not bought a second one yet, but I'm finally due). However, once you have it right, the look using the Back to Black is just as good, maybe better. I don't think one attracts dust any more than the other, and I'm still waiting to see how long it stays looking good. We're expecting rain tomorrow so I'll see how that goes, but the concensus seems to be that it holds up well and since I put it on several days ago I expect it will. What I'd like to see is how well it resists streaking right after application, because the Meguiar's needs a little time to cure before you get it wet. I'm also going to treat adjacent panels in each product next time for a side-by-side comparison.
