Iglue only gave me a day's hold too. You might try CP ORWG, or get BA to send you the rest of the Perma Rite #15 that I sent him to see if it works better for you.

With these glues, I can get at least a two week hold.

Caveat: I don't comb my hair back. I don't think I could get a good-looking two-week front hairline with these glues without learning some new techniques. E.g, perhaps the ones that MB just posted.
