I need to address several areas of creeping rot, thanks Ohio winters! Problem is I am in an apartment and all of my real tools are 12 hours away. Are there sanding/grinding attachments for cordless drills? I looked in the big-box stores and they had nothing. Areas are around two wheel wells and back window. If I can get them sanded, I have POR to apply and plan to finish it off with a coating of monstainer. Any advice is most welcome. Thanks in advacne
