I found my problem. I'm old and senile. I'm the same age as my truck. The paint supplier has a rat rod black and a rat rod satin. I bought one of each at two separate times. One from the store and the other was online. After a short visit to the trash can I found one of the two cans. The other can was being used and on the bench. By the time I realized what I had done it was two late. Each can of black have a different gloss ratio. So I called the store and found a new flat black, Dead Rat Black. I sprayed the cab today and I is flat. Thank's all for your attention to my delema.
