What’s the best way to sand a pickup bed’s slots?? Is there a tool that gets into the slots better than holding a full sheet of sandpaper? I want to get it ready for a “Rhino Liner” type liner, and I have lots of chunks of old dried paint that needs to be removed. I don’t want to strip it with chemcials as yet, it is way to messy, and I don’t want any run off to hurt the paint under the bed.
Thanks,
Doc
