Why does nobody talk about using a soapy water mix for checking small window seals?

I tried it on a tricky bathroom window job last week and it showed a tiny leak the bubble test missed. Has anyone else found a better way to spot those hairline gaps before the customer calls back?

My buddy swears by a spray bottle with dish soap for finding those tiny leaks.

Brian's right about the spray bottle. I've found adding a little glycerin to the mix makes the bubbles last longer, so you can really see where the air's sneaking out. It's cheap and you can get it at any drugstore.
