I just repaired a rust hole in my mailbox with PC-7. It cures in 24 hrs. but stays soft for about 4hrs. It is sandable, so it is probably carveable too. I have had it for years and I don't remember the cost. It is in most hardware stores. It is blended and is a putty. It is in a small two lid tin can. I need to use spell checker also. lol.
