First of all, the problem with Quick fix is that they only give you 2 oz. and that barely makes it to the line.

All of the experienced "subs" here (including myself) will tell you to buy 2 bottles and take them both with you to be safe.

As far as a little leaking out, I see no reason for that to be of any harm to the wizz except the fact that you DO NOT have enough.... Go get another bottle right away or your wizz will be rejected!!
