Wow! Never had this happen and would like some input from everyone.
I have done in the neighborhood on 15 tiger wraps and never had this problem - but really it doesn't have anything to do with a tiger wrap - just thread!
I wrapped the bottom layer ( 3 different colors ) of NCP for a butt wrap tiger, then I burnished the threads as usual to achieve the "wavyness" , applied a light coat of CP to hold everything in place, dried overnight, then applied the 1st coat of epoxy.
mixed epoxy in a mixer, poured it out to flatten, quick flash o remove bubble, applied the finish - at this point I noticed more bubbles appearing than normal, but I didn't think to much more about it,
just a quick flash of heat and they were all gone. I had to leave 5 minutes or so later. When I returned 2 hours later I had 8 pretty big bubbles in my finish!! WHAT THE !#$*:%/+%!!!!!!
1. what do you guys think happened?
2. What's the best repair or should I strip the thread and start over?

I would have used at least 2 coats of CP on the under layer

Had the same thing happen on a Tiger next to the winding check but I believe it was air trapped under the check. I fixed it but it was very discouraging.

Use a razor to cut the top off the bubbles and try another coat of finish.

Thanks everyone for your responses. I actually had gotten home in time to flash the air bubbles out but the crater stayed there. I cut it them all out after the epoxy hardened, and applied another thin coat of epoxy - looks great- like there was never an issue(even with a magnifying glass). Lucky me - THIS TIME!
After, thinking back at my process - I believe :
1. I left the rod too early - if I had been there another 30 min or so checking the finish - I could have removed the bubbles as they appeared.
2. I also usually apply a pretty thin 1st coat of finish (real close to the threads for 2 reasons (to reduce air bubbles and to keep the finish from getting too wavy) - I think I applied the finish too thick(for what I am use too anyway!)
I just wanted to do a follow up post to thank you all for the responses and give the outcome. while I am sure the repair I did will not always come the way this one did - it was worth a shot, and this time it worked beautifully!!!
And finally, what I take away from this is like everything I learned from day one (mostly from the builders on this website) :
1. Get a routine that works for you and REPEAT IT EVERY TIME!
2. Never rush ANYTHING while building - If you don't have the needed amount of time to complete the step you are working on - then WAIT UNTIL YOU DO HAVE THE REQUIRED AMOUNT OF TIME NEEDED!!

Rule of the day:

Don't leave the rod for examination every few minutes for the first 30-40 minutes or so.

That way, if you do see a bubble develop, you can hit it with a bit of heat and get rid of the bubble/s.

Be safe

Heat can actually cause more micro-bubbles that take a while to show up. Two coats of CP would have helped.
I tried all the finishes in my cool basement shop and found Threadmaster to be the best behaved in my environment. I NEVER have a need to apply heat (other than warming the bottles beforehand) - simply blowing on the finish with a straw makes them all disappear.
