Very impressed with my recent order from AG on Black Friday. There were some crazy discounts across the store which enabled me to pick up a few products that I had read some good reviews on. I've only had a chance to try the Blood Tonic so far but have been amazed at how well it works. I had previously used Wolf Chemical's De-ironizer v2 and Bilberry but the combo still left a lot of older brake dust that refused to budge. Blood Tonic has managed to work some magic and I think a couple more hits should get the alloys free from the last of it. Looking forward to trying out Alkalloy and Spar-tar!
