I replaced the lower quarter panel on the passengers side but the drivers side had been replaced when I don't know. I want to seal these sections with POR15 and it is impossible to know what dirt is in this crevice I couldn't get to. I made a few tools to dig it out and am continuously pulling plain old dirt out of there. I need to get it clean enough to etch and apply the POR15. I made some tools that maybe some of you might want to make for the same dilemma.
