I would have reservations about using a power buffer on a vinyl rear window because, as you have noted, of the softness of the plastic and for some other reasons also.
The next reason would be because of the tendency of power buffers to sling the compound all over the place. This would get the polishing compound all over your convertible top and would be a pain to get out of the fabric, if you ever did get it all out.
The other reason, and for myself it would be the most important one, would be that it would leave swirl marks on the surface that will effect the clearness of the window.
