Redken Shades EQ Crystal Clear-please help!

I am sort of green when it comes to using pro color (reformed drug-store color girl). I got some Redken Shades EQ in Onyx which I've used before and also bought some blue kicker from the same line to mix with the Onyx.

 

Here's where I need your help...I'd like to get the Crystal Clear shade and use it to seal the color afterwards. If y'all can answer the following questions so I don't f-up my healthy hair it will be much appreciated and I'm sure you'll be entitled to some good hair-karma:

 

1) How long after coloring do I need to wait before using the clear gloss?

2) How long do I leave the gloss in before rinsing it out?

3) What ratio would I use of developer to gloss?

 

Thank you!
