THIS IS EXACTLY WHAT I HAVE IN MIND DOING WITH MY WORN 5904 FRAME, FRIEND. THE GUY I TALKED TO DOES ALL SORTS OF STRIPPING FROM MAGNESIUM TO ALUMINUM ALLOYS. HE SAYS AFTER THE GLASS BLASTING, HE CAN RESEAL IT, BUT HE DOES NOT CONSIDER IT NECESSARY, AS HIS 10+ YEARS IN THIS BUSINESS SHOWS THAT THERE IS NO SUCH NEED. HIS WORK IS MOSTLY AUTOMOTIVE COMPONENTS, FOR LAND AND MARINE ENGINE PARTS, ANTIQUE CLEANUPS, AND PREETY MUCH ANYTHING THAT NEEDS MEDIA BLASTING FROM TINY THINGS TO STATUES AND CASTLE WALLS. I TOO AM CONCERNED ABOUT THE ANODIZING GOING AWAY. WILL THINK ABOUT IT, AND PERHAPS STAY AWAY FROM THE RAILS, AND OFCOURSE THE INSIDE OF THE FRAME WHERE ALL FRICTION OCCURES. THANX EVERYONE!
