Sealing PVC DC Ducting

I've had my cyclone DC for a number of years and never sealed the PVC duct connections. My initial thought was "let's see if this works ok" before doing anything more permanent. I'd really like to avoid PVC cement if possible so when I move, I can reuse the ducts with a minimum of effort.
I know that plain old duct tape is a very poor choice.
It appears aluminum tape is a much better choice but I know from experience it is nearly impossible to remove from a pipe once it is applied.
I'm curious what people have used to seal their PVC ducts.
