I added wood shutters on my home in Phoenix about three years ago and they face East and have no shade. In the summer the front of the house gets really hot!! I have been using the Wood Whisperer's varnish formula of marine varnish, naptha, and boiled linseed oil on all of the other wood and they look great. In this instance, the shutters are almost completely heat marked (like you set a hot coffee cup on a finished table). I'm looking for any advice on how to fix this issue. Not sure how to insert the images which would have been good for you all to see.
Appreciate the thoughts.
