A resin based fluorescent paint with decreased drying time and improved fluorescent durability is formulated from a resin present in a concentration of about 55 percent to about 65 percent, by weight, an active solvent, for and compatible with the resin, present in a concentration of about 5 percent to about 10 percent, by weight, a gelative additive present in a concentration of about 1 percent to about 5 percent, by weight, a rheological additive present in a concentration of about 1 percent to about 5 percent, by weight, an anti-skinning additive present in a concentration of about 1 percent to about 5 percent, by weight, a fluorescent pigment present in a concentration of about 20 percent to about 30 percent, by weight, a synthetic drier in a concentration of less than 1 percent, by weight, and a wetting agent in a concentration of about less than 1 percent, by weight. The paint of the present invention is particularly suited for the purpose of detection of vibration loosening or tampering.
