That's gonna pop when you get finish applied!
Fun thing about Juniper is there always will be one more crack to deal with.
When I work with resin, I just use some form of sander with a coarse grit to get through the waste.
I found that even though the resin is hard after a day (fingernail test), it is still "gummy" and will grab any tool that gets near it. 48 Hours later, much better!.
Reading up on the various resins out there, they all seem to have a different time-to-cure spec.
