What is the effect of UV rays in Del Sol nail polish?

Nobody really knows for sure so this is your opportunity to become involved in product testing and discover the truth. All you have to do is apply Del Sol to the nails on one hand and brand X to the nails on the other hand, then go on a Caribbean holiday and keep a daily diary on the condition of each nail polish. When you are finished you can write up your thesis and you may receive your diploma if it is considered satisfactory.
