Seed Dressing

Can anyone help me with advise on how to Seed Dressing. The reason I ask is that I have have about x3 months ago started a worm farm in an old bath tub and get a lot of worm juice out from it . Have researched and read that the worm juice is very good is as it coats the seed with nitrogen and bacteria, giving the seed a nutritional boost when germinating.
However I am not to sure what the procedure or method is or how to go about seed dressing, as would like to give it a try this spring with Brassicas, French beans and Sweetcorn, Seed Dress some and others germinate as normal and compare if there is any advantages or benefits.
I was just going to put about 12 seeds at a time in a tea strainer and soak them in 100% fresh worm juice for 15 min to coat them and then sow as normal.
