How to fit rivnut / nutsert to frame?

I have an old steel frame road bike, dating from 1980. Its not rare or special, but its very like the one I rode to high school in the late 80s.

Problem: There are no bottle cage mounts, so my solution is to drill 4 holes and fit rivnuts to suit the standard bottle mounts. Rivnuts are also known as nutserts, and look like this:

There's a special rivet tool that compresses the fitting while preserving the thread. I have one on order, and it looks like this.

So other than drilling the bare minimum diameter holes in the frame, what else do I need to consider?

  • paint or treat the raw steel edges of the drilled hole?
  • locate holes properly on the centerline or fractionally left, away from the drivetrain?
  • use mixed-epoxy on the insert as an insertion lube plus it will be a waterproofing layer when in use
  • my nutserts are smoothbore, not ribbed as per the example - would this matter?
