Dear Geoff,
As of now, we are able to quote to you as precoated fins and can manufacture the them.
We are very lucky in that the materials can speed up importing materials from vendors faster in two weeks.
But we don't make a quote for supercoated coils because it has a higher price, as you mentioned.
The quotation for you, we will send it to you asap with precoated fin coils
Thanks and Best regards,
Somkuan
