It works ok for me in Perth :shrug:

I use the spf 50 ‘sport’ version on my legs and arms (not the face, too greasy) and it seems to do the job OK.

I guess if it’s 35 in testing that’s still OK-ish for general use. I do really plaster it on. And as I’m usually doing that before a lot of outdoor work, it draws a further protective layer of sand and dirt to itself…
