: I've had good luck using a Purdy paint scrapper with a slighly

I also find a scraper the best tool. With care and a bit of practice, a scraper allows precise feathering of the edge of the top layer without digging in to the first layer. I tried a cabinet scraper, and it worked but dulled quickly. I now use a carbide scraper made from the "bit" out of a cheap knife sharpener. It works well, was cheap, and stays sharp several times as long as a steel one does. The piece of carbide had sharp corners which I rounded slightly on a grinder - this reduces the chance of damaging the first layer of glass.

Good luck,
