Homebrew PCBs

What about GOOP  It is made by Eclectic Products  Just tried going to their webpage to be sure I got the right link but can not seem to connect to the page.  They do show up in a Google Search but the links don't seem to work this evening.  It is sold at a lot of places here in the US.

I know that I used Fish Aquariums which has silcone to seal the seams.  For my first 3 tanks using Ferric Chloride and they all leaked after a few years.  Changed to using Plastic storage container.  Only had the Ferric Chloride in the Plastic storage container tanks for a year or so never had a problem and have had some Ferric Chloride stored in a 5 gal. Plastic Paint Bucket with lid for over 4 years and has not had any problem with leaks.  

Right now have CuCl in a covered Plastic Storage Container that is sitting in a larger container and so far have not had any problems with leaks.  I gave up on the Aquariums.  Myself I did my tanks so I can put 4 or so boards in at once with the Ferric Chloride so far with the CuCl I lay the board flat, normally a 8" x 10" or 8" x 12" with air bubbles.  I know that US Plastics www.usplastics.com sells some tall narrow Plastic tanks for PCB etching.
