Uses for worn multitool blades

[suther51]

When it comes to sanding I have yet to find them as good as a random orbit on wood or auto body, except where a random orbit wont fit, ie corners but they still dont leave a good surface, too many scratch marks. As a plunge cutting saw, with a sharp blade there is no compare- with one exception, my old Fien, too fast, too short a stroke = too much burn, with any blade I have tried in it. The m12 and m18 Milwaukees that I have correct this problem well. When i worked on old cars we tried them with rubbing compound on finish paint with shop grown felt pads, seemed they created too much heat. The paint would get a smeared look to it. This was before all the clones came out so fast and short stroke, the newer clones with longer strokes may work better. We did a tremendous amount of hand rubbing out of paint and were looking for better ways to do it. Back to the leather pads n rags by hand. Soo I can see the potential in polishing metal with them, right pad n right compound I can imagine good results but have not used them that way. Never know opportunity may come around the corner, so thanks Olderdan for the post.
