Yeah i'm very happy with it, i can't take the credit though. My mate's a carpenter and he done it, i just stood over him and pointed!!!. I'm sure you can get that stuff to add but with gloss paint, i'm not sure you need it. Gloss paint is water proof anyway. I have a clear acrylic sheet on the inside of the tank(resting on glass shelves) so that stop any moisture from rising from the tank into the hood. Also the slits for the filter would help with air flow if needed.
The LED's i have are only cheap RGB's strips off Ebay, they have a sticky backing on them. As you can see, my DIY skills are basic and i started to install the LED's at 9pm on Christmas Eve!!!!. I don't mind because nobody see's them, although i do have the pics in my Albums and have posted them....
