Close but no Cigar
I have nothing against NH Northern. But even though their machine in nice looking it is another cash cow set up just a step above the tote machines sold on ebay for way to much money..
I use 3 to 5 lb of sand in my mixes and use a seal rite. the NH machine could not spay that material..
You could just go buy a water pump and any kind of tank and it would do the same as their machine.
All they would have had to do was add a mixer and a air pump set up and it would be a decent start up machine
