The heat cure IFU is wrong
I spoke with them over the discrepancy between the powder bottle processing technique and the IFU last month. They were unaware that it was different.
I gave them a respectable time interval to make their own announcement. Big boats turn slow and all that.
They have not. So I am.
They said you should *not* boil for only 30 minutes, that the IFU is wrong, and the bottle instructions are correct.
The proper short cure cycle is:
You should always boil for 60 minutes, after 90 minutes at 165F.
