One good thing is to mask off the fin.Smooth it out with a number of diffrent things,dowels,old credit card corner, tongue, ect.
Are the holes from bubbles? Is there a way to avoid this? Or a good way to fill them after the first coat is dry?
Never tried the tongue. Tried a depressor. Will try licking them and see if that works though.
OUCH!!! What a DH!Ah, answers I can use. Will try to slow down and do more smoothing on the next batch and resign myself to a little post fillet work.
Also no hard feelings on the comments. Sometimes it's frustrating, or more frustrating when already frustrated by a build, when the first response is not much help at all.

... Tips to get much smoother fillets that need way less attention after hardening???

Not a dig at anyone.
"Anyone" means exactly that. Anyone. Not someone. Don't try to read more into it. Just good to get answers. This forum is sometimes hard to navigate. And is sometimes frustrating when you want a specific answer to a specific problem. If it was a dig at anything it was the search feature and how useless it can be.
... On my builds now I use micro balloons instead of collodial silica as the additive. Strangely enough, the Collodial works well as a filler with hobby epoxy. I now use micro balloons on the outside fillets and I get a perfect fillet, just requires some sanding and filling.
H... Then place wax paper over it and lay the dowel on top and wipe off any abundant excess.
Just an idea that might suck. But it would seem that if you use a pump to measure, perhaps you could add the filler to the epoxy before the hardener is added. Then stir and let sit for bubbles to rise. Potentially, one could pull a vacuum to get bubbles out before adding the hardener.
