1/8 " will drill Clean through with little enlargement of the hole, and a 3/16 will work well for zipping the heads off.

I prefer just taking the heads off with a 3/16, it is much faster than drilling clean through.

The drill bit sizes for the 3 sizes of rivets that Airstream uses are as follows.

1/8 rivet # 30

Olympic rivet # 21

3/16 rivet # 11
