In a shady spot, squeeze out just enough SOLAREZ to fill the damaged area, no more than 5 mm at a time. Put the lid back on the tube.
Cover the repair site with a piece of smooth and clear plastic film. This will keep your fingers clean, so you can shape and model the resin and give it a glossy finish once you're done.
With the plastic in place, work the resin into the damaged area, and eliminate any bubbles.
