I used radiaplex gel. Excellent stuff! I still have some left & used some a couple of weeks ago when I took my kids swimming at a lake & sorta forgot the sun screen! I had a pretty bright red sunburn that night & put radiaplex on & was gone the next day! Probably not so smart on my part to even get sunburned to begin with considering the massive radiation exposure I've already had! I spent two weeks in Honolulu in April of this year & with diligent sunscreen app's I didn't get burned once! Erik
