I am a newbie needing your expertise. I am building my very first ship model which is the Hasegawa IJN 1/350th Isokaze plus Lion Roar Kagero PE. I didn't realize how tiny those PE parts are! I am currently having difficulty affixing the guard rails on to the gun and torpedo turrets (later the smoke funnels). I have lost a couple of guard rails already in the process and I ended up buying this set below as replacement.

When I view pictures of other modeler's works, these were affixed very beautifully and cleanly. Any advice on the proper approach? Does anybody have a technique to share? Do I need to drill holes? CA or PVA? I'm getting frustrated but I'm not giving up yet.
Hats off to all of you who have made this process look easy.
Thanks in advance!
