It works great to strip factory paint off your Transformers! I've just started working on Recon Ironhide and wanted to remove those weird silver stripes. Well, alcohol wasn't working, so I tried sanding, but couldn't get in tight spots. Then I remembered what I learned from my two year old. While trying to clean some of her artwork off my wall, I realized that this thing takes off paint! Well, I tried it on Ironhide and BAM factory paint came right off! Took minimal effort and worked great, and the spongy texture gets into the tight corners. I don't know if anyone else has tried this, but I knew I had to share. Hope it helps.
