Glue is for holding things together not holding things apart except if you mix Kevlar microfibres with epoxy then you can hold things as far apart as you like.

Use a scalpel not an Exacto they don't roll

For making fuel proof cowl mountings drill the screw holes as usual and make sure it all comes out right then remove the cowl and redrill all the holes with a 3.5mm drill, roughen the surface of some golden rod inner and push into the hole. Secure with a few drops of thin CA and trim it off flush with a sharp blade. You have a fuel proof, vibration proof, resilient screw hole that will grip the screw even if you take the screw in and out several times.

Use old antenna tubes as balsa drills exactly as the description for brass tubes above.

Finally... Never make a mistake you can't put right.
