Okay, im at work at the moment. Ill make the payment...
yes thats normal.... if i not training to much 14 days and rubber dead with bubble ... h3 blue sponge not good, broke very easy ...
Bubbles are ALWAYS a risk when you boost, no matter how careful you are. The extra tension from boosting weakens the topsheet to sponge bond, and can come loose from the impact of the ball. In general Chinese-made rubbers have a weaker bond between topsheet & sponge, so it's more likely to occur.
Yeah i always put glue first then booster. Three very thin layers (the booster I use is Seamoon) . Leave it for a week and then glue it to the blade.
Thanks a lot for the info mates!
