Blue Aqua Sealer is a water based cosmetic sealer, used for sealing such products as Reel Body Art Inks, Makeup effects, prosthetics and more. A light spray is usually all that is necessary. Don't over do the spray as it will eventually build up and wrinkle. If you feel you need a second coat, dry the first coat before applying. A blow dryer will accelerate drying time. There is a matting agent in the product to create a satin sheen. Make-up may be used right over sealer to give temporary tattoos, or any body art, that under the skin surface look. Water based - waterproof when dry. We call this "the sealer that seals all the other sealers."
