#45956, "RE: modelling the ocean floor for a wreck model" In response to In response to 19
Eric, how I told before, the concrete dust is not absolutely the best solution. This is only an attempt for to reproduce the ocean floor without paints, water or other. Probably is realistic, but not the best.
Consider that the thickness is approximately of 1mm, the model will be inside a box. Even if there is a minimum quantity of dust, will not be possible to breathe it.
