I gave everything a good cleaning and then primed the base and the wrought iron candle holder with Tremclad Spray Primer. Then I sprayed both with a light purple Krylon.
I balanced the glass coaster on the top of the candle holder, on the three arms, and adhered it with the GOOP glue. I then left it to dry until the next day. I had to make sure the coaster was very securely attached before I glued the glass bowl on to the coaster.
I love the purple!
