I figured. But isn't there a type of CA glue that's safe for clear parts?
I experimented with clear expoxy glue and it seems to work fine, except I can't get rid of the bubbles during mixing and it gets incorporated into the kit. For small applications, the bubbles aren't too noticeable but for larger build-ups this is a problem. Good thing I only need it in small amounts.
Edit: To get rid of the bubbles, I kept adding in small amounts and sanded in between applications.
