This year when Bourque Industries started to make Kryron in quantity, so as to become commercially viable (the ability of a business to compete effectively and make a profit), the scaled-up equipment used could not handle the high temperature requirements of making Kryron and halted scheduled delivery to Mims Motors.
Thus the decision by Mims Motors: "lack of materials [Kryron] that were needed to meet production deadlines, and EPA approvals."
I'm sure, in the near future, once Bourque Industries obtains commercial output of Kryron that Mims Motors will start using Kryron for it's superior properties over what they were forced to switch to today.
