This forum has been a great help for some of my projects so I'm giving back. About a year ago I stripped a set of 80s Ludwig concert toms and could not find a suitable product for stripping the remaining adhesive. I had tried Citri-Strip, Zip-Strip, Xylene, Lacquer Thinner, etc. This stuff was very stubborn.
I have finally found something that attacked that adhesive like none other: Soy-Gel. It started working within 5 minutes and I simply removed it with a plastic scraping tool. After which I removed the residue with lacquer thinner. Very minimal time and effort was involved. Also, this product is very safe to work with.
