you can still see roller marks with the rope light on, just not nearly as bad. I may just bite the bullet and spray it.
Not to insult your intelligence, but I got a great tip from the paint guy at HD a few years ago on eliminating roller marks. Work one 4'x4' area at a time. Start in the corner and do the square, then do the same area directly underneath it. (I know you're doing the ceiling, so whatever you want to call "underneath"), then when you have done an entire 4' section of the ceiling from side to side, take the roller and run it the length of what you just painted. Do this for the whole ceiling keeping a wet edge and it really works good on the roller marks.
thanks for all the updates!
