Rebound 25 is usually super reliable. If the layers on either side of the poorly mixed layers were well mixed, cross your fingers and give it some time. I apply super thin layers, over and over, on top of each other.
If the inside layer, the one touching the mold is poorly mixed, start over. That first layer is critical for preserving detail!
For me, the outside is usually more drippy but smooth looking. I also cut little pieces of yellow foam and embed those in the middle layers to help make registration blocks and cover it with Freeform Air. When making a hard outer shell for the Rebound, actually have holes where the registration pieces bulge out, it helps create a vacuum to hold the Rebound to the hard outer shell.
If you cannot wait and don't mind the wasted Rebound, pull it off and start over. Otherwise, I'd give it a few days and see if it cures.
