Crazy idea, but is it?

OK, So the wife has me sanding some 1950's era metal porch furniture. It has 3 layers of paint on it and I'm not trying to strip it to bear metal 100%, just areas like the rails that you would touch. I have a cheap Ryobi corner mouse sander; yesterday at the Home Depot (buying more 80 grit) I stopped and checked out the nice DeWalt sanders, 12,000 opm, although the stroke is shorter than a gnats ......,

but could this be used for detailing? and does anybody do it?
 
All other parameters being equal, a machine featuring a large stroke (or offset) will create more centripetal force than a machine featuring a small stroke, because centripetal force is the primary element that causes the backing plate to rotate.



Therefore, if you use a machine with a large stroke size, you should generally see an increase in random pad rotation versus an identical machine featuring a short stroke. If the orbit offset is doubled, the speed of the backing plate is also doubled; however the abrasive ability is increased more than double
 
I have thought about something similar for getting into small spaces that a DA is too big to get to. I think it the short travel on the oscillation would require a very thin pad. Otherwise the contact surface of the pad would just sit in place while the upper part of the pad would just flex around it.
 
Funny Thomas, but I was not planing on using sandpaper, I was thinking flat foam pads, why? well, with the short stroke it would render the microfiber useless - I mean, like surbuff, if the whole trip of the wiggle is equal to or less than the length of the microfiber strand, then it would essentially just dangle in place. Thinking about this in animation really helps. I'm thinking something like those burgandy cutting pads Megs had, man they were tough and ridgid as a Marine at attention.



And I haven't ruled out 3000 grit, think of a daily driver, 4-5-6 years old, paint oxidized, water spot etched and faded to hell. After the APC wash, clay, you're looking at least many hours of buffing away. Why not 3000 grit, then polish, wax? OK, you're thinking holy cow, sanding and only 1 polishing step before wax?? Are you insane? Remember I said neglected daily driver here, not brand new 599 - MF pads and polish will clean up 3000 grit, heck, 1500 grit with no problem. OK, you say, but why not just break out the wool and rotary? Fair question - Here's my reasons for NOT, with a rotary, you either tape everything or you wish you had, or maybe you LIKE using a tooth brush to clean compound sling out of a windshield cowl. Skill, I can run a rotary, but what about the guys that are leery of these? Price, that DeWalt at Home Depot was 80 bucks, new Dewalt rotary is a bit more.



I'm not saying this will be my new go to method, I'm just saying it could be an alternative to what we all are doing now.



And I'm looking for comments from the friendly folks here.
