I think my filler is too soft...
 

After glassing over my quarter skin seam, I started skimming with some Marson Platinum, with about a 6 inch spread from top edge of skin down. Some parts of the bottom feather in very nicely and smooth...looks like a cloud to me. Other parts are scratched and jagged...can't get that nice smooth transition. These parts are probably from a different mix. I can actually scratch it off along that edge with my finger nail. Can't do this along the pillow soft edge.

I'm thinking I didn't quite get enough hardener in the mix. I'm ready to take it off and redo. Unfortunately I have a pretty nice level cut. Should I redo or am I overreacting? I applied it over epoxy sprayed two days previous.

RE-DO for sure. There is a good possibility you also didn't get the surface scratched well enough for it to stick.

Or clean enough, you don't want any dust in the scratches,
especially for filler transitions.
I learned that the hard way too.:thumbup:

Re-do fer shure! If you can scratch the surface with your fingernail the problem is just rearing it's ugly head, Paint will be a nightmare and you will be kicking yourself later, it's much easier to do this now. :thumbup:

Get it off and redo it ...

It's come off. In fact before I even had any answers here I wasn't right with the fact that I could scratch it away so I started taking it back off. I think I obviously mixed it a little too lean. It was a hot day when I was applying and everything was kicking so fast.
