Resin cures solid by exposure to Ultra Violet light and will cure more rapidly if resin is covered by an Optifilm strip during the cure. Cuplube lubricates suction cups. A crack is filled by sliding the bridge suction cup along the crack. Cuplube speeds the sliding action. Ultra-violet light solidifies liquid resin.
Some cracks fill only from an entry hole.
An occasional narrow crack rejects resin. A small hole drilled into the crack may allow resin entry. A black syringe simplifies injector refill. A black syringe is used to transfer resin from bottle to injector, black to lessen chance of sun damage of the resin. A sharp probe eases glass shard removal.
