On for the base! This is some car repairing mastic, quite smelly stuff that I fluidified with Acetone. You can't see much as the white sort of crushes the contrasts but the ground is designed so that it looks like a mud pool with plenty of rills coming out from the vehicle.
Problem: it already bent the plastic base I used -I know it was a quite stupid move from me to use a simple plasticard base for such an aggressive product to use on top, but well.. I feel pretty tired these days
