You will likely find that the white glues don't bond very well so the clear parts can be easily knocked off. It's a compromise over risking fogged parts but one that, in most cases, is acceptable.
If a stronger bond is required, the best solution is to dip the clear parts in Future floor polish, allow them to completely dry, and then use CA (cyanoacrylate) glue to attach the parts. The Future prevents fogging of the clear parts.
