great for curing whatever [SEP] i must admit i do not use this conventionally rather than curing polish on my nails i use this to cure uv resin and nail polish on flies the kind you fish with most fly tiers use a uv flashlight to cure one fly at a time but i can stick several flies in this uv lamp and cut down on time spent the timer function is especially handy based on the lamps performance on my flies i wanna say it should work wonders for fingernails
