Well I've gotten my first rudimentary (railroad track) anvil and am working on getting it cleaned up (was covered in rust, etc) and secured.
In the process I decided to try some of the wet/dry sandpaper I'd picked up the other day just to see what kind of finish I could pull off with it.
Much to my surprise, it appears the local hardware employee hooked me up with the wrong stuff despite my having asked specifically for sand paper that I could use for metal.
It sanded very nicely for a little bit, but almost immediately lost all its grit. Upon further inspection I see that it doesn't mention specifically being good for metal, and I assume it must not be designed for it.
Anyway, I was wondering if any of you folks had some advice about good types of sandpaper for this sort of work?
Thanks in advance for any insight you might provide.
