Hi! I'm printing a transparent part in SLA resin (via a service -- not printing it myself) and it will live submerged under a few inches of fresh water. I've been researching trying to decide which coating would be best to use... I've come across suggestions for FlexSeal, PlastiDip, clear acrylic spray, and epoxy coatings. Is there one that would be the most durable/reliable? Or a different, better option? The part needs to remain transparent after coating. It's part of a lighting effect, so the finish should also be glossy/smooth, i.e. not matte. Thanks for any tips!
