Luckily no issues yet here. I remember my mom and aunt rubbing us down with baby oil with methiolate in it at the beach to "get a good base"
I generally spray sunscreen when I am going to be in the sun a few hours, and I can't remember the last time I burned.
Ironically, with the same amount of sun on our honeymoon in July, my Cuban wife got a little burnt while I stayed my same pasty white. She was better about reapplying than me too, I generally just sprayed when leaving the room
