The other day I was finishing some acrylic pens with the Micro Mesh pads.
I used very warm water instead of the ice cold tap water.
I noticed (accidentally) that using the warm water provided a much smoother finish than using cold water does.
My blanks were pretty much finished at 3600 grit, but I went thru all the grits anyway.
When I finished going thru the grits, the acrylic was like glass.

These are the same pads I've used on other blanks, so it wasn't like they were a new set or an old set. I only used them on 4 pens so far.
The blanks were the other 1/2 of a set already made so it wasn't a different acrylic either.

Just the warm water made all the difference.
I thought I'd share something of use to everyone.
Thanks for reading.

I’m guessing the warmer water cleans the sanding pads better. If hot water it might soften the plastic a bit. Warm water would sure make it easier to sand in my cold shop. I’ll have to give it a try too.

Hmmmmm; I remember reading somewhere (one of those "amazing facts") that water actually changes viscosity with temperature. Cold water is more viscus than hot water and with the proper equipment it is measurable.

I used to argue against this, then I went into the industrial water treatment business and found out it was true.
