it has to be something changing with the brushes if they sucked before and are good 1/2 a year later.all the same conditions and different results.the only thing different were the aged brushes.there has to be something effecting the brushes over time.sun spots,location of the moon and sun while the earth is a slight angle,i dont know but its something.
