Look. As bad a job or how good a job they are gonna do doesn't matter. Where I grew up, you accept your losses with no complaint and be happy for the people who beat you no matter how unfair it may or may not be. Besides, I think SaMaster will make a pretty good mod.
I've also heard that rubbing alcohol works. I might have to try with both!
Rubbing alcohol is not really effective. It removes Gs and the attribute symbol which could be something you don't want. It can also be used to remove ink but I do not hink it removes the base paint on the baku nor the accent paint.
It could also be possible that the acidic properties of aerosol in a spray could have adverse effects on the bakugan if it is at all possible to get a cloth saturated enough with the spray type.
