S4 spoilers versus GTS spoilers

The S4 rear spoilers are black and the GTS spoilers are painted. Are they made of the same material? If not, where can one buy a GTS rear spoiler for painting and installation on an S4? Aftermarket works as long as it looks like the original.

Thanks

My GTS spoiler seems to be made from fiberglass, my S4 spoiler seems to be a bit more rubberized so they aren't the same.

If the rubberized S4 spoiler is sanded down smooth, it can be painted over so there is no need to locate a very difficult to locate GTS rear wing.
