Same area with a little sanding and neat skim. Definitely no bubbles. Ready to add some balloons and start fairing.

Definitely worth your while to put a weave filling coat on within 24 hours. Or even 48 with a light scuff.
Re: What’s enough “tooth”?
I had spots like that, not enough epoxy. At the time I hadn't heard of a neat coat so I used a wire brush to scratch everything up, very time consuming as I got a little OCD about making sure everything was roughed up.
Fallguy, where did you get your roller? I've not seen one like that before and, since we have moved, I have no idea where mine went. Heck, the only thing I've been able to find is my fiberglass tape and cloth. I've had to order new stuff like epoxy and fillers.

Called a bubble buster.. mine is 1/2" x 6"
Re: What’s enough “tooth”?
A heat gun or torch (do this outdoors and don't breath the fumes!) will make the epoxy soft and come loose from your roller so it can be used again. It's recommended to keep a bucket of acetone to drop the roller into once you've finished for the day. I've heard that acetone will remove set epoxy, but I'm not so sure about that, especially if it's already cured.

I’ve used vinegar and a toothbrush (before cure) to extend the useful life, but the vinegar eventually makes them rust.
What do you do with the heat gun/torch method? Just clamp it to something and use a pick to get between the fins when the epoxy softens?
Thanks.

If you take the roller off and find all metal parts; remove the roller and set on a piece of steel and burn it with a torch; it takes awhile; then drop in a bucket of water and use a wire brush to clean it.
None of the epoxy should be gummy; all burnt to a crisp and when it hits the water it'll almost all explode off the roller from CTE.
