there have been multiple coatings...
the original coating plain and simple sucked....it was a ceramic coating that was worth about 3 cents.
the next coating was crap as well. Although Marty said the coating was thicker and better, it was not holding up either. A lot of people had issues with their coatings. I had this particular coating (which was the "NEW" one at the time). I had them Jet coated....
The "NEW" coating is an OPTION.....You must pay for their NEW OPTIONAL coatings. It is the same as Jet-Hot according to Marty and others who have seen it. This is what he is charging an extra $40 for. If you do not want it, you don't need to have it.
I hope that helps in explaining.....
