JET-HOT has sent me a coupon worth $25 for any order over $200.
I do not need it.
If you can use it, let me know and I will mail it to you - free.
It is the company that applies Ceramic coatings to various engine and exhaust parts.
They coated my 914-6 heat exchangers - really increases thier lifetime.
