I wrote a little glue FAQ that is located here:

If anyone has anything that they think should be added, I'm all ears.

Personally, I have the best luck with a combination of Perma Rite #15 and CP ORWG, and can easily get two weeks, or even three, using them, even though they are white glues.

I have a question for others: I certainly can't get two+ weeks and have the front hairline look good, as glue seeps into the hair and causes hairs to bunch together, etc. I haven't worried to much about this, since I don't do a full exposure of my hairline. Unfortunately, even with a partial exposure, it can be problematic. My current best solution to this is to just use gel to make my hair clumpy to begin with, and then it's not noticeable.

I've read that people do partial cleanings of just their unit fronts in order to prevent this problem. I assume you have to do this before any glue seeps into the hair. If so, how often do you do this front cleaning? And you are able to do this without weakening the rest of the attachment?
