I really like your lighted monument sign. Are the Garden Pavilion letters flush with the surface or are they a layered on the inside? Sounds like you have a well proven procedure for sanding. I've had some luck with those sponge sand paper for some finish work. So far I haven't had to work on items that need to have the high finish factor and I primarily work on lighter colors. I'm still pretty new at this with a lot to learn.
I recently purchased one of those little sanding triangle attachments for a multitool. It is about 1" wide and 1 1/2" long. That works ok for getting into carved tight areas where hand sanding gets tiresome. I use that on my cheese tray board since pocketing out the interior to a depth of .15" causes a line around the exterior of the pocket. My 4" ROS won't hit the tight areas. This 7x10" tray has 3 areas that had to be hand sanded, the top left and top right corners and the bottom curve (top is where handle is).
