IIRC, JE calls for .005". I used .0045" (or .0005" less than JE what specified). Please double check with JE, because I could be wrong. I called them & asked, which they were glad to provide.

I remember .003

Call JE because I think it may have changed somewhere along the line.

Whew, that's good news for me. That's one of the things I've been worried about.
