Much better and I believe it will get better still with another trip to the Kroil tank. I'm glad you didn't feel the need to resort to wire wheels or sandpaper!
Yeah, I thought I might have to do my fine steel wire brush but the pads I have seem to do the job just fine. Not sure another round of Kroil is needed - Just some more effort on it as is will get what is left.
The stock disc is a pain to get rust-free though. Got it mostly done but the areas where the disc edge touches the stock takes a long time.
Anyone know what the process is for disassembly of the bolt? I had dunked the whole thing in the Kroil, but I do want to take it apart and clean it out.
