hello,
i have a few brides that want to add shimmer to their cakes. does anyone know a product that is clear and not colored. i can only seem to find colored shimmer sprays.

You can brush on pearl dust. The "white" is actually pretty clear. It adds shimmer to white or light colored decorations without changing the color too much. Here is a link:
