I have quit using high build altogether. All I use now are Flex-Cote Lite and LS Supreme.
Multiple thin coats are the easiest way to go. Less bubbles and it's easier to get that smooth finish.
Hint: Don't sweat the bubbles TOO much on the first coat. You can always slice them off with a razor blade.
It gets easier as you get more practice.
Guess ya gotta build some more rods!
