Good job. I must say that if you look at the first woofer I did, that it was WAY beyond bleaching,the glue was red and the dustcap(s) were faded so all one could do was use the method I developed. As for increased mass, I've got to stress that there is almost ZERO gain, a FRACTION of one gram (the LE14a has a mass of 142.6 gms). The product I use WILL NOT PEEL in time. I think that the bleach pen is a great idea!. It gives us an easy middle ground and quick fix to the problem. I have to raise one question though. I remember when I was a kid that I soaked a pair of shoelaces in bleach, not realizing the effects that it would have and when I went to get them out, they FELL APART!. I am curious to know what the long term effects of that bleach sitting in the Aquaplas is, especially since it is in a concentrated gel form. I'm not raining on your parade, I am just posing a question that might otherwise be overlooked. In any case, again, good job and thanks for sharing your new discovery!. Steve G
