I don't know that I'd call it a problem but I've had mixed results using Future to protect clear parts from CA (I usually use Slo Zap). I typically dip clear parts in Future shortly after starting a project so they're ready when needed. I don't recall what the model was but one time I used CA glue on a clear part (not on purpose but rather because I wasn't paying attention) and there was no hazing. Assuming I was on to something I did it again with a truck model and got moderate hazing. Why I did it a third time remains a mystery but I did and again got hazing. Every time the Future had in excess of a week to dry. In my mind the outcome is clear. I'm not using CA anywhere near clear parts and because I can't think of any reason I'd have to anyway I've put the subject behind me. If someone has had better results please left us know about it.
