I have used both Aero Shell 33/64 and Red and Tacky.

If you look at the Product Data Sheets Aero Shell provides more info, and is .mil and .gov approved. If you look at the common areas on the PDS's most of the ASTM numbers are the same. Pretty sure both are okay. Red and Tacky is easier to come by.
