Shiny Pattern on Stretch Fabrics

Does anyone have a good technique to add a clear, sheen layer on top of stretch fabric? I've come across many times I need to accent a fabric with an additional layer, but the pattern would be too small to build each section. Like the octagon pattern on Daredevils' Under Armour below. High-gloss spray paint? Clear fingernail polish? Maybe a clear, rubber-like spray paint?

Has anyone had any experience with this??

Thanks, all!
