When there is enough liquid (booster) in the sponge that there is less air in the air pockets of the sponge: this would make the sponge no longer responsive and it would be compressible but it would lose some of its elasticity and rebound-ability.
Yes but you didn't explain why.
Liquids don't compress much whereas gases do. You fill your tires up with air for a reason. You don't fill your tires up with oils or boosters.
Zeio and I have a lot of disagreements, but we agreed that the foam rubber could be permeable or non-permeable. An example is wet suits and dry suits used for diving. Trying to "boost" non-permeable foam rubber is futile as the oil will not penetrate into the foam rubber.
So what kind of rubber do you have? Permeable or non-permeable? I would use the scraps if you keep them after mounting your rubber. I would put some booster on the foam rubber and see if it penetrates to the other side. Easy. Question answered for all time. Even if you replace old rubber then use it. Separate the foam rubber from the top sheet and test it.
I don't give a hoot if my opponent boosts or not. I know it doesn't help them and they are wasting a lot of money.
Boosting is a scam. Does anyone want to refute my claim?
And yes. I am baaacccckkkk!
