Hi Rodmann 99999, Glue and fabric won't add a half gram of mass and it is not on the cone. Final qts won't change by .01. This mass will not be noticeable. I agree with your last post, but Bob doesn't need an "o"ring. 25 or 30 years ago, I did recones, I built and repaired speakers. To make it clear, I do not want Bob to use paint at all, only clear latex skimmed off the top of un shaken or mixed latex paint. Hopefully Bob will have some old paint in the garage or basement. Bob would be making a very pliable glue. It would work great in this instance. I've patched several surrounds, if the tear isn't large, it will almost not be noticeable. Bob, in the end, you can only do what you are comfortable with. This is my best advice,
good luck, Tim
