Often I just use a cotton swap (Q-tip) inserted into a small bottle of CDS to soak up as much CDS as possible and apply it to my skin. If you are covering a larger area, you could use a cotton pad soaked in CDS. DMSO can follow that application and I usually use my clean fingers for that.
I have found that CDS applied to a problem area on my skin may not be very effective unless I break the skin around the area so it can penetrate into the skin, and even the blood system if I can get the area to bleed a little bit. This idea is similar to pricking the skin before an application of black salve.
For the Patch Protocol, I would saturate the cotton gauze pad with CDS as Jim's book describes when using MMS1. He recommends 7 minutes maximum contact time the first time the patch is applied, and if no negative reaction occurs, increase the time up to 15 minutes for the next application. I don't think that will be necessary if you use CDS.
For spraying the skin with CDS, I have used a small plastic spray bottle. Remember to keep CDS out of light and kept cold so when you use it, less CLO2 gas will escape.
Yes, the chart for non-ingestion use would apply for skin applications and other protocols as well, such as a
Douche Protocol.
Those two charts you see almost made their way into Jim's latest book. In fact, they were included during the proof-reading period, but at the last minute he removed them! Perhaps they will appear in another publication some day.
