Drying times are not the only advantage toothpaste builds have over HX.
Come on buddy. Would you want a toothpaste built house?
The HX appears superior in every way.

BTW, an interesting idea would be for the HX arm to have a hose fitted to it to poor the insulating material into the cavity of the walls before it departs.
This makes sense to me as their next application.
They are already onsite so may as well spray insulation into the cavities from their dynamically stabilized position. This would improve insulation and create a better wall for customers. The cavities between blocks could easily accommodate this insulation which would only be possible on double brick, bricks used with mortar.

Not investment advice. Do your own research, etc. etc.
