Water pump sealing tips?

Water pump sealing tips?
I've decided to deal with my cooling system once and for all and replace pretty much everything. Does anybody have any sure-fire tips or tricks for making sure the water pump seals 100%? This will be the third time I've had to put a pump on the car since I've had it (Second time was after the HCI so that shouldn't count). I'm replacing the thermostat, water pump and all the hoses at once. My thermostat is already installed and the timing cover has a mirror finish on it after getting all the old gasket crap off. Thanks all!
Here's a video with about 16psi in the system using a pressure tester. It never leaks like this when it's running, but some of you may remember my thread where something went haywire and I had coolant all over the engine bay ( https://mustangforums.com/m_3537553/tm.htm ).

At work I use air craft glue from the parts store. Its really tachy and seals pretty good. When you buy a new water pump make sure you pull the backing plate off and put some on both sides of that gasket too. It will never leak. Also when bolting down a water pump I always try to make a cross of the bolts tightening them down so nothing warps.

The main thing is getting rid of the old gasket material correctly or you will be pouring something out of your waterpump or timing cover. Silicone isn't going to solve the problem if that is the case. I didn't clean my timing cover off all the way of old gasket material and ended up spilling oil everywhere a few days later and had to pay to have the cover cleaned in a local shops parts cleaner (worked like a charm). I then used the black silicone to adhere to the cover and problem solved.
Same thing in case with the waterpump. It's just really important you didn't put any gashes in the timing cover/waterpump or there will be leaks!
