Hello Alpay, i can help you with that issue.The video that is around the net with the guy boosting a rubber with falco (if im right) is a very nice tutorial, but found that it does not work right with baby oil.
My advice is:
.Remove the factory glue that comes in the H3 neo and leave it resting for 48h.
.Put a mask on and apply a thin layer of lamp oil, then leave your rubber rest for 24h.
.With the mask on we use the baby oil for first time, another thin layer.
.After 24h, put one layer of Revolution 3 glue and when it is completely dry, the last layer of baby oil.
.I like to leave the rubber resting for at least 5 days and last step is to glue it, 2 layers on blade and 2 on rubber is what works better for me.
To be honest, it is not like falco or other boosters, but is really nice what you can get from a 20 euros rubber just being patient and working a bit.
Hope it helps.
Kind regards.
