I have a friend that used it for a national show last september and ended up a very strange green color the night before the show. They got her fixed in time for the show, but it was a very stressful situation. My handsdown favorite was to be airbrushed by jan tana. Especially since they will do touch ups for you if you end up needing touch ups. EX. I peed on my leg on accident between the morning and the evening show. I was horrified! The drip ran from my mid thigh all the freakin way down the back of my leg. I bout died of embarrassment. But they fixed it in a jiffy, and I stepped on stage like nothin ever happened.
And after the show? I just wiped myself down with baby wipes and then we went out to dinner. Tan that was left faded in a few days and non of that nasty splotchy lepery lookin stuff that pro-tan caused when I used it before.
Hope this helps! Im sure others have had good experiences with liquid sun rayz. Id definitely do a trial run and try it a few weeks BEFORE your show. Don't wait til the day of to test it out. Just in case. Don't want you ending up lookin like Kermit the Frog.
