Bob,
I know people who have tried the Solumbra products and swear by them. I personally use the Columbia hats, shirts, and slacks. They must work, since I can put them on, use 45SPF on the back of my neck, ears, and hands, and I can stay out in the sun at the flying field for about 5 hours without any redness.
Mike,
It's not the sun you got since the advent of sun screens. It is what you got for the first 40 years of your life. I grew up on the beach in Ft. Lauderdale. My skin cancers started popping out at age 45. Since then, I have had 12 squamous cell cancers surgically removed and the numerous frozen ones as you said. I feel your pain and pray that they get it all. I have been lucky. I have only had one that had to be dug out again a few years later. God bless!
