I like Espree High Sheen Finishing Spray on sale here:
Espree Natural High Sheen Finishing Spray for Dogs & Cats
...also like Pet Silk Coat Control Finishing Spray and John Paul Detangling Spray is okay without build up.
Chris Christensen Ice on Ice gets high praise, but I have not tried it. Always mean to but just have not gotten around to ordering.
I look to make sure it is more a detangling/conditioning spray than a control spray. The control sprays are like hair spray and more inclined to build up in their coat.
