Even though this comes up fairly often, I still find this topic sorta interesting. People often assume that clay removes LSPs, sometimes from their own past experiences and sometimes just by assumption. I do not believe the "proper" claying removes an appreciable amount of LSP, though it will remove *some*. From my perspective, it's a simple matter of my knowing what I've experienced many times. It's something that, IMO, anybody can prove to himself (or herself) by experiencing the same thing. I've shown it to nay-sayers in in-person demonstrations and you can prove it yourself.
Sometimes I'll inadvertently seal in some contamination when refreshing my LSP and I'll spot it at the next wash. It takes a much more aggressive approach to claying to remove this "sealed in" contamination than it does to remove "regular" contamination.
Here's a simple way to prove to yourself that *gentle* claying doesn't remove much LSP:
Find an area of your vehicle that has a little speck of contamination that you would normally remove by spot-claying. Something that's on there good enough that minor rubbing *without clay* won't remove it (not something that'll easily wipe off).
Apply your LSP to this area, right over the contamination, and buff it off normally. Now you'll have a freshly LSPed area with the contamination sealed away under your LSP. Note that this experiment will work best if the LSP is something sorta tough (Zaino/SG/Collinite will work better for this example than Souveran, for instance).
Next time you wash the vehicle (the experiment will work better if you let it go for a while), clay the area in question *very* gently, using either your clay lube or wash solution, or *something* to keep the clayed area well lubricated. Clay as gently as you can, a lot more gently than you normally would.
After a few gentle passes, *not enough to remove the "sealed in" contamination*, look at your clay. Even though you were being unusually gentle, you'll probably see dirt on the clay that has been cleaned off the LSP, but the contamination will still be there. This is the kind of claying that I do. Enough to clean the LSP, but not enough to remove it.
Now clay more/harder and see what it takes to cut through the LSP and finally remove the "sealed in" contamination. It'll take a lot more than what you did earlier.
