It's tough - requires steady hand and confidence which means you have to mess up a few ;) to get to where you want to be.
I also will use testors clear parts glue to attach delicate parts as well. No crazing and you can clean up and oozes/drips with a damp q-tip. No where near as strong as CA, but more forgiving for sure.
When I do use CA for these types of things I use the thick slower drying type so you have a few seconds to position.
With this Lotus Coventry climax, you have clear glass on paint, then mirrors on glass! This is where the testors stuff is a must (or a plain elmers will do).
