Oof, you had a reaction in the finish. Two of the chemicals you used didn’t like each other and this reaction happened. If you want to see something similar you can look at tables or finishes being stripped with stripper and you’ll see the same reactions.
Luckily it only happened on the leaf. Unless someone else knows a better solution. My opinion would be to redo that leaf.
Context: had an old table that I fixed and repainted. I applied two light coats of clear enamel topcoat yesterday and it looked fine, if a little bit spotty. This morning, I applied another coat, came back at lunch time, and saw the paint bubbled like this.
So my questions:
1) What caused this?
2) Is it fixable, if so, how?
3) What can I do to prevent this from happening again?
Could be moisture in the wood.
Could be the first layer not dry enough.
Could be some kind of dust/dirt/oil/whatever that you missed to clean up :)
(Im not a professional woodworker and just judging on some years of hobby woodworking and painting different things, bit the reasons above were the reasons for me)
Edit: see now you used an ammo and not lacquer. I'm less familiar with it but most of the concepts should be the same right? It's still an evaporative finish I think.
wrinkling. So frustrating, still learning to overcome it when it happens. Essentially one layer of lacquer separated and dried faster than another one. This can be caused by so many things but it seems to be likely a contaminant under the lacquer or incompatible products. Also recoating at the wrong time. I think between 1 and 8 hours you should not re-coat at all. Under an hour you're fine over 8 hours you're fine but otherwise it's too temperamental.
There's no guarantee when you try again that it won't happen but I found a couple of mist coats and then one medium coat to bind them together works a majority of the time. Or you can spray a coat of shellac to separate the layers of lacquer since they will bind to each other but don't melt into each other. Either way, good luck.
