I have a query regarding tool for fine grinding.
Currently I am in a process of making 14 inch mirror. Rough grinding is in progress. For the fine grinding (or even polishing), can we create the tool using general purpose M-Seal. While I was reading about it, I got to know that its waterproof, less curing time, crack proof, moldable, etc.
Has it been already tried by anyone? Any thoughts regarding this.
