As much as I like carving wood, when it comes to a nicely
carved sign which is going to be covered by layers of paint, I prefer
carving the HDU media.
When carving a sign or sculpture which is going to reflect
the qualities of the material, then the use of wood is the overall champ.
The conclusion here, is that usually when your sign is
going to be painted, I will use the carving media unless your sign is being
left natural and the wood grain is important, or where you specify your
desire to have wood used.
If you do not specify wood, I will use either pine or the
carving media. Most of my signs are still being carved in pine since I have
use for the wood chips.
There are several manufactures of HDU but I prefer
Sign•Foam3 as my carving media of choice.
Finally, no matter which media I use, you are going to be
getting a Terry Wolff Creation which will provide you with many years of
enjoyment. If it is made of wood, as long as you keep it protected from the
elements it should last as well.
Thank you for taking the time to educate yourself,
