I don't understand the logic of putting in the pink stuff only to blow it right back out. That does not make sense to me. I would do one or the other, but not both.
And if it were me, I would just blow out the lines (pushing a lot of air through), add pink stuff to the traps, and call it good.
I used to pump the pink stuff through, but went two winters (with temps well below 0 for a week at a time) with just blowing out and no issues.
Because just blowing out "might" work just fine, but it is not a guaranteed way of getting all the water out of the system. Displace all water with pink, then drain. Leave pink in the traps and maybe some at the bottom of the tanks at the knife valves. For three years of storage, I would leave quite a bit in the toilet too, or some other long lasting lubricant.
