Another cool thing about the Luxi compounds is that they contain no
crystalline silica that is harmful to breathe. So the pre-polish
like Luxi gray and black are not toxic and will do major scratch
removal safely. Also theycontain water soluble vegetable binder so
very easy to clean up. One more advantage to the Luxi pre-polish is
less metal loss as it uses aluminasinstead of silica.
Silica is a course media and must cut and scrape metal to remove
scratches. Aluminas are flatter platelets and actually cut and
burnish as it removes scratches, the result is less metal loss and
less detail is loss.
