Review on Blue Demon General Purpose Aluminum by Ron Thomas

I'm tentatively giving this filler 2 stars as I've only used about 4 refills of it. I experienced an unbearable amount of sweat pollution on these 4 bars. I've tried to clean them with everything I have. They may need to be thrown away. I even took some soft aluminum flower wrap wire and welded it on to make sure it wasn't my method or my base material, it welded cleaner than this filler. I'll give it a few more chances and update this review if the filler needs a re-evaluation.
