Hi, @Zwill!
Have you by any chance tried Matra Pro? I wonder how hermetic the sponge is?
Yes, I tried it and it works with Mantra Pro too but not as well as Butterfly spring sponge. Literally nothing comes close to spring sponge X.
Newer ESN stuff also not bad. Old ESN stuff like G1 are not good. Mantra Pro in between. But maybe Mantra Pro doesn't need this.
If someone uses Chinese FH and G1 then just use booster.

I've tried this with 09C and it domed after 6 hours at 1.5 bar... but then back to flat within an hour. No noticeable effect on H3 under the same conditions.

What about performance of 09c afrer air boosting?
Felt a little harder and faster. I'm guessing this would change pretty quickly over a couple of hours, but didn't experiment enough to say more. No question it temporarily expands the sponge. Use case may be more like speed glue than a typical booster. May also be useful for re-gluing rubbers that shrink a lot.

In my opinion, product is not "ready" yet... needs more research. For example if it is "pumped" with Helium, Nitrogen, CO2 or other gases, what happens then? Do the rubbers become lighter? Is the effect lasting more? We might have a NitroPoweredBlade for ultra spin&speed!

Or nice fireworks in case, let's say someone used Hydrogen!

:p :p :p

Definitely needs more research!

Just a protip, don't boost Glayzers with oil. It just makes them worse. Softer, less crisp less ball hold, less grip. Just avoid it. Air boost doesn't do that at all so air boost good, oil boos bad. Dignics and possibly tenergy and rozena the same. 🤧🤧🤧
Air boost ftw.

Reading so many positive comments inspired me to build a pressure box. In my case, a pressure cylinder from cooking pot. So, I test some rubbers at 1.5 bar for 24h.

The results (I played only with the first 2):

Spinfire 1.7mm plays a bit faster 2h after treatment;

H3N national not boosted - initial 0.05mm increase in sponge tickness, but no notisable change in speed after 2h;

Victas TDE - no bending after treatment;

Degu II 2mm - no bending;

H3 provincial without boost - same;

Flyatt spin - initial bending that goes 90% away after 1 hr;

Andro R42 - same;

Omega V tour - same;

Musa I - a bit better;

Mark V 1.8mm - twice better than mentioned above esn rubbers (good responce).

Update:
Marder II - good responce;
G9C - good;
G1 - not so good;
Slice 40 CS - very good;
T05 - very good;
Mantra pro XH - no effect.

That Mark V bend is pretty surprisingly serious as I have been saying that more modern pored sponges tend to pick up the air better and leak it slower. From all the rubbers I tried still Butterfly Spring Sponge X is the best by far.

Even tho Spring sponge rubbers also get flat from doming after an hour but their play is much better after. Victas V15 is also a very good example that can be very effectively air boosted.

I air boost my Glayzer every 2 weeks. And I avoid playing with it after boosting, I let it "deflate" for a day or two.

And compared to any other solution you don't need to take off your rubber form your racket with this. That is a huge bonus. Also it's quite consistent since one has a pressure meter, and the rubber doesn't change weight. Using booster oil is more difficult, no meter to tell you where you are and need to re-glue etc...
