Is it okay to continue to idle the car with engine and brake lights on with liquid coming out of radiator? It says to idle for 20 minutes

The system should be sealed as the product circulates though it for the 20 minutes.

Does it use Sodium Silicate?

Nowhere on the bottle does it say sodium silicate.

I have a 1999 ford ranger. running fine now but it is getting older. can i use this as a preventative? or do i need to wait for a problem to show up?

The way K seal works is by seeking out leaks in a pressurized system. I feel you or best bet would be to wait until you know your leaking coolant. I use this in a truck about 7 months ago and I still have no problems with the truck. Work very well

can i make a 100 make a 100 mile trip 10 minuets after i put the k-seal in...

Yes! It does it's magic within 10 minutes. Just don't drive it too hard for about 20 minutes. Drive smooth. Highway driving or a good road with a consistent speed is best. After 20 minutes, you are all good!
