Ok... so on my first cage building venture I planned to build wooden, waterproof boxes. I had been informed (since I know next to nothing about this) that epoxy will 100% waterproof it. Well that person came down and did them in fiberglass resin, I was led to believe from that that they were indeed the same thing. Nope! Weeks later and much of the stuff is sitll totally wet and won't cure. I contacted the chemist that worked for BONDO (the comany that made fiberglass resin) and he set me straight, and confirmed what all the other people we contacted at marine places, etc. has said. Fiberglass resin is highly water-resistant, but not waterproof, it is finicky to work with, and will NOT cure over any painted surface, only bare wood or metal. I can save my enclosures however, I need to remove all uncured areas with acetone, and the epoxy the entire surfaces. This will seal with reamaining fiberglass resin and any stripped areas as well... phew! I'm not sure what I may have said in my previous posts regarding any of this, so I am passing this info on to correct any misinformation shoudl there be any, to forewarn anyone that has successfully worked with this that they were very lucky, and to anyone considering these procedures, so they do not make the same mistakes
Take care.
