Maybe, but then I had also rubbers that were reverse curled right out of the packet.
That can be a temperature problem, where they either packaged the rubbers before they cooled down, or the temperature when they're made is a lot different to where it's used. Since the top-sheet and sponge have different expansion rates at different temperatures, it will result in a dome (or a re-verse dome).

keep it on as long as you can either when you bubble or some part of the rubber come off. Then change rubber, no need reglue or reboost. Each h3 should least 4~6 months easily for the casuals here.
I had a sheet which I boosted pretty heavily. I played with for 2 months, then didn't play for 2 months (so 4 months total) and when I tried to play with it again and it felt super dead. I reboosted it with 2 thin layers and after about 3 weeks it feels like it's losing some pop, more noticeable on softer shots (I usually start my FH practice with minimum power and gradually increase it to game-level power). I'd like to keep it at a fairly consistent level, so I'm trying to figure out exactly how long I should use it for so that there isn't too much of a change when I switch to a new sheet. I play/practice about 10 hrs a week.

It just occurred to me that when I remove my rubbers (H3N 39 commercial and H8 80 37), they always curve inward. A LOT. I think this means my sponge is shrinking right? What could cause this

I'm also thinking of boosting with baby oil, would that help?
Wow, that’s serious, have you tried vitamins? 😉

Cheers

buy a haifu white from tt11 or haifu yellow/black from prott.vip. Get the 500ml no15 glue. Then follow the below

steps Below only works for h3 blue sponge 40 degree 2.1mm

1. open package
2(optional). if u want to cut your rubber to save on glue/paddle you can. Like cutting the edge off etc...
3. 1 layer of haifu of your choice (white/yellow or black w/e).
4. wait 24 hours
5. 1 layer more layer of oil
6. wait 24 hours
7. 3 layer of no15 glue
8. 1 layer of oil
9. wait 48 hours
10. 2 layer of glue on blade then stick the rubber on it
????

play until rubber bubble, or rubber come off by accident, or top sheet oxidized(could prevent that if you just keep it clean every so often). which could be 6 months or more.

ordered.. the rest I have.. when this doesn't work I won't believe you anymore!
