Eliot, I definitely did that earlier today. I think it was you that suggested it on another thread at some point. I use the heck out of the search feature on this forum. I usually always search before asking questions. That video was very helpful and priced out Lexan on my trip to HD at lunch.
Carl, I saw exactly what you mean with the color. I looked at the dot and asked the guy if he mixed it haha, it looked white. Its okay, I was contemplating blue or white, so this will be perfect I bet. No worries at all about "the applecart," I welcome all ideas, changes, suggestions. As far as the access spot, I considered just leaving a hole there, but I could definitely just make it a hatch and leave the scenery on it.
If my drywall mud (final skimcoat) has dried the way I hope, I should be able to maybe get the room primed and possibly one coat of paint on tonight, we will see.
