I have a question for all you resin casters out there. I'm about to cast a clear epoxy resin piece with translucent pigments that will be exposed to long periods of UV (sunlight), and saltwater. I have read that a lot of clear epoxy resins 'break down' or go yellow with sun exposure over time so I would need a UV gel coat of some sort. Because it will be exposed to saltwater should I use a latex or urethane clear gel coat and would it be ok to do it as a second 1-2mm cast over the epoxy casting for the gel coat? I also want it to be quite durable to scratches and shock proof. So which would be my best option? Thanks in advance all.
Well, yes and no. A mirror will reflect the light but will not give off a glow. That's the nice thing about a white wall because it reflects the light while also appearing to glow. What I would recommend is diffusing the light at the bottom of the shaft. This could just be a thin white sheet. Try it out, but I think you'll find that the sheet will make fill the room with a pleasant glow that pretty much fills the room. edit: As for the reflective tape, I'd stay away. It might make it brighter, but the light it will give off is not very pleasant. If it were pleasant, why would they use it on caution signs? The purpose is to simply draw attention to it.
Sure, just do as you would with any other car, go slow.
