I have used Auric Illuminator II for about 1/2 year now. This is the improved formula over the original. I've now treated over 500 discs counting SACD's, DVD's, and CD's. Every single one sounds much more real, live, dynamic, detailed, with much improved bass also. I bought 2 kits and am still one the first one with about 1/5 of the solution left. I did have to buy an additional pack of 10 Staedtler black markers. however at a cost of $17 total delivered. My good friend and I have compared notes on the AI II and added at least one area to do because of the improvement it offered.
They have instructions in the kit. I do about 5-9 discs at the same time so I don't have to wait long for things to dry. Do the same step to each disc before going to the next one. This is what I now do: 1.) Using the marker on the label side, paint the inside edge of the center hole on the disc; 2.) use the template and center the disc, hold it in place with your off hand, and paint the entire inside of the disc that shows through the large hole in the template; 3.) mark the outside edge of disc; 4.) paint the label side last 1/8" carefully; MARKING IS DONE; 5.) cut about a 3" x 3" piece from one of the cloths provided and fold it so that enough to make about a thicker 1.5" piece to apply the solution with; 6.) put 1 drop of solution on the label side of disc and use the layered cloth to rub the solution all over the disc including the parts marked already; 7.) after all the discs have been done, start this step with the first one and proceed in order thereafter--use a different whole cloth and fold it so it is about 3" x 4" but several layers thick. Buff the label side of the disc until all the dried solution marks are gone; 8.) once all the discs are done, turn the disc over so the shiny side is showing and hold it by the edges. Add 1 drop of solution on this side and rub it with the smaller folded piece all over the disc; 9.) after all discs are done, start with the first one and buff with the large cloth unit the disc has no dried marks and is very shiny; 10.) return it to its case and mark the edge of the case with the marker--I made a solid circle about pencil eraser size so I know this disc was treated.
