The black paint works but you have to use the right paint.

It's like taking 1 step backwards and one step forward. The backward step is
the insulation value of the paint layer & the 2 steps forward are the
increased radiating properties of black verses silver or dull grey. High
efficiency teat sinks are anodized black for the same reason.

Subject: Honing and cylinder painting

I've been looking around the web during my lunchtimes for reading material
on rebuilding etc., I found a site called aircooled.net that has some
interesting and detailed information on it.

In particular, I was looking for information on hone stones to be sure I had
the right grade etc being sure of oil application during the process, etc.
I have a Craftsman cylinder hone that I used once some years ago, I do not
recall the stone grade.  Is stone grade critical for light honing of used
but within spec cylinders to seat new rings?

Also, in one document, it is recommended to put a coat of black hi temp
spray paint on the outside of the cylinder fins to aid in cooling.  I always
thought painting a heat transfer surface was akin to adding a layer of
insulation??  Not true?  I didn't plan on painting anything but the brackets
and tin and cast housings etc.

Thanks in advance for comments.
