Im not sure what bigger issue you could create, it already leaks.
Just get a sheet of sandpaper, put it on a flat surface, tape the paper to the flat surface and make circles. There's really nothing to it. Start with like 600 if your worried about taking too much off. Then new gasket and sealer, done.
