I do wish I was more skilled with wood, there are some light leaks. Oh yeah for the white paint you want outdoor paint due to the high humidity and water splashing.
Hey guys, food for thought:
A buddy of mine made his own canopy (to save cash) but it soon turned out that his lights were "gutless". He was dragging his feet about buying new lighting because he's "thrifty"...
He ended up applying a new coat of polyurethane and then, while it was still wet, he applied some aluminum foil (Reynolds Wrap shiny side out).
It cranked up the light intensity but would even fix light leaks.
Just a thought.
