Regripping a used overgrip?

[firearc]

I've used it for 1-2 months and I'm thinking about regripping it with less overlap and put a new overgrip on it because it's currently too thin(G5), so it'll be original + 2 overgrips to make it G4.
Is it bad to take off the overgrip and regrip it? Will it be less sticky?
Do I use 1 or 2 finishing tape, for 2 overgrips?

Just stick to whatever suits you, it doesn't matter what grip size it is just go with anything that your happy with.
If your happy with your current grip size then 1. replace with a thin grip or 2 replace with a thick grip but probably remove the original grip so it feels the same like when you bought it.
