A method of finishing a composite panel, the method comprising:

• applying fiberglass resin across open cells of a honeycomb core on opposing surfaces of the honeycomb core;
• curing the fiberglass resin to form fiberglass skins bonded to the opposing surfaces of the honeycomb core, wherein the applying and curing of the fiberglass resin on the honeycomb core forms the composite panel, wherein each of the fiberglass skins comprises pores or pin holes formed during the curing of the fiberglass resin;
• sanding each of the fiberglass skins with a sanding machine;
• rolling a layer of liquid UV sealant with at least one roller onto each of the fiberglass skins such that the liquid UV sealant fills one or more of the pores or pin holes;
