1st time boosting question

[PhantomCSS]

Sorry, i know this is a frequent topic but these are genuine questions that i didn't fully understand after reading and viewing alot about this topic.

12h after 1st layer:

3h after 2nd layer:

I was wondering, how much curl is too much?
How little curl the rubber should have for me to glue?
And if i should add a 3rd layer of booster to the STN

Obs.: right rubber is a Reactor Corbor (using it for controlled testing as i have another unboosted), the left is a used Sanwei Target National BS Medium-Hard and the booster is the Haifu Seamoon Commercial version.

This looks fine. I usually check it on the table, and if it looks like the left one in the picture below and dry, I glue it.
I wouldn't give them another layer.

Hi, dear
You should consider to possess this nice accesory in your stock or you incur troubles with the curled and domed sheets. Again, be aware that Butterfly factory always using thermo-pressure machinery to get the blade and rubber together.

Be happy all.
