There are companies who mold large sections of rock and trees and pull very authentic looking castings for uses in museums and displays. That's all they do and they're very good at it - and expensive. My technique looks very close to the real deal and is done very fast. My trees can stand on their own (no wraparounds) and can fit anywhere they need to.
My fiberglass rocks and caves are textured with bondo, painted and stained. I always liked placing one of my huge boulders in a path and tossing it aside in front of unsuspecting people. Of course it only works on people who don't know me or what I do.
