With slight magnification a green rim on the top limb of the solar disk can be seen on most clear-day sunsets. However the flash or ray effects require a stronger layering of the atmosphere and a mirage which serves to magnify the green for a fraction of a second to a couple of seconds.
Rust-OleumÂ® Specialty Chalk Board Spray converts surfaces into a usable chalkboard. Apply to metal, wood, plastic, hardboard, glass or paperboard. Erases cleanly. Indoor use only. Cleans with soap and water.
After the Chalk Paint has completely dried (not cold to the touch or damp) you apply a thin layer of clear wax. You can use the wonderful wax brush or a piece of cheese cloth or a rag. Then, if you are choosing to tone with the dark wax you would apply your dark wax AFTER you have applied your first layer of clear wax.
