I tired Amazon.ca and seems like it does not have it.
if you have a chance buy ATTBLIME 3D Scanning spray , cheaper and has lower layer accuracy of 3 microns compared to AESUB BLUE 15 microns .
is the Gray color best?
There is not gray 3D scanning spray , the Blue don’t means it is blue , it is just a color code for a type of a 3D spray .
Thanks for the clarification.
