Those would Be sweet, but I'm still not making what I'm doing clear. I'm working on small, like motorcycle and add I'd parts that aren't attached to anything....I have to have one hand free to hold and manipulate the part and the other to operate the rotary. Hence why I need small, not just 3" and why I've always used the air polisher. I'm just looking to replace it with an electric replacement. Holding a full size with extensions or just even a 3" backer isn't gonna get it. I primarily use this after wet sanding parts to get my paint gloss back. This is all used on fresh paint.
