Damp Sanding question

[mwoywod]

When damp sanding, I've been using rinseless wash D114 @ 1:256 (or Mckee's N-914) in a trigger sprayer and in my bucket with mirka abralon discs rather than a drop of dish soap. I was hoping Mike or someone else who does a lot of damp sanding could give me their opinion on the matter.

From my understanding, people traditionally used 1-2 drops of dawn because it helped provide additional lubrication. My question is, could any soap be used or does it have to be dish soap? For instance, could I use a quality car soap like a few drops of hyper wash or optimum car wash? Even though they have gloss enhancers I don't believe they have wax? Personally, for the past 20-30 orange peel removal jobs I have only used D114 at the tradional 1:256 dilution and it seems to work, plus I don't worry about allowing it to dry on the paint and it's easier to remove. I tried to use ONR but I'm really fond of the sudsing action of d114 and N-914.

If anyone has any personal suggestions or advice I'd love to hear them. If there is a reason to use a drop of dish soap that I haven't considered I would love to know!!! Thanks!!

It also helps to reduce clogging of papers or discs.

Any soap.

The best soap used to be Meguiar's #00 as this was both a body shop safe soap and also low sudsing soap.

I will tend to use whichever car wash soap is closest to my hand... just a few drops... otherwise when machine sanding you'll create frothy foamy suds. Not a big deal but you want to be able to see where you're sanding. Espeically raised body lines but a trick for these is to tape them off with a thin strip of painters tape or 3M blue vinyl tape.

Mike, I can't thank you enough for taking the time to respond. I will try using a little bit of car soap instead tomorrow. The reason I prefer using a rinseless, like the new Mckee's 37 N-914 rinseless wash is because I feel like it's safer to allow it to dry on the paint. But if it's not providing adequate lubrication and reducing clogging like a car soap then I need to be using a traditional car soap.
