Squeegeed it dry, waited a few hours with it out in the sun and clearcoated over it in late afternoon.
I'm running out of warm days so I decided to block sand it today. All is good except for an ever so slight discoloration / blotching I'm seeing in the middle of the decal in places (this was after 1000). As a test, I sanded a tiny little part of it further and it got bigger.
I'm wondering if anyone has seen this before and might know what it is. My best guess is that I should have waited another day or two before block sanding. To deal with it, I'll probably clear coat it and try again.
Hard to see in the photo but here it is:
