Welcome to R2R! Lots and lots of good folks here with incredible experience. Yes, I've done the same type of repair. Removing all the old silicone is a chore for sure. Cleaning the frame and the glass surface with denatured alcohol so the surfaces are perfectly clean is a challenge. I seem to remember wearing new cotton gloves to keep finger oils off the surface. That's one of the keys to a good seal. Cheers!
