I'm not sure if this is the right forum for this question. I'm asking here in hopes that someone has dealt with this. If this is the wrong forum, please do not vote me down. If necessary, I'll simply withdraw the question.
I need to apply labels that indicate switch functions to the exterior of an electronics enclosure that will be used outdoors. The enclosure is made of polycarbonate and fiberglass. The labels must be permanent, waterproof, UV-, chemical and abrasion-resistant.
I've tried applying water decals and coating with epoxy and UV-resistant clear top coat, but the results are inconsistent.
Any recommendations? I'm not looking for a specific product (as I think this would be against forum policy), rather for general guidelines. Do you use commercially available label material or some other solution?
