Yeah, I did. My son likes to use that SPF # 1, which is basically baby oil and iodine. When I got too lazy to reach for my SPF 50, I used his crap. Now, I've got blisters on my shoulders and starting to itch. I hate that!
I use SPF the highest I can find. Otherwise I burn like some sort of mutant. I think when I was at the coast it was something like SPF 98, and I still burnt.
