Cleaning Clay

[Byas U Nambisan <Byas_U_Nambisan@ccm.fm.intel.com>]

While washing/waxing my A4 I noticed that the paint surface has small 
spots on it (like tree sap).  Also, my clearcoat has a few scratches on 
one side where a bird dumped on it and I tried to remove the dried 
remains with water and a towel.  Hmm, it just struck me that I've not 
had good luck with birds - my A4 has gotten dumped on (unknown perp) and 
pecked at by horny wild turkeys.  BTW, I solved the turkey problem by 
getting a garage for the A4.

My question is, what is a good way to get rid of clearcoat scratches?  
On a black car they show up clearly.  Also, I saw an ad for Cleaning 
Clay by Griot's Garages.  Thought I could use that to get rid of the 
tree stains.  Has anyone used this?  Any other tips/inputs?

Thanks,
Byas
