i'm thinking about a wire wheel attachment for an angle grinder for quick,no-nonsense removal of remaining rust in my trunk floor.there are a lot of angles,channels and grooves as well as sharp edges as i have removed all the horizontal trunk floor except for each small section on the left and right that joins the inner fenderwells as it is salvageable.i tried a da sander with 36 grit but it is shredding from too many sharp edges and really isnt the right tool for the job.any suggestions?thanks.

thanks anyway,i think i gotta handle on it.
