Spot Clear Coating

["Walton Curl" <WCURL@mail.mcg.edu>]

Does anyone have a suggestion about "Spot Clear Coating"  I have a small
area that needs to be repaired, base coated and then clear coated.  My
understanding is though,  that one has to shoot the whole fender again. 
I would think there must be a way to simply spot coat that area using a
different thinner-  Anyone have any suggestions?  Thanks
