a pain, but sunburn is worse. UV
is expensive and not to everyone's taste. Instead,
treat your own
cotton, rayon, or silk clothing to make it sun-protective. Some clothing is inherently protective, but you can easily burn right through a new shirt, especially if it gets wet. A couple of boxes of either of two different brands
of a wash-in UVA/UVB blocker will invisibly increase the SPF of a whole washer-load of clothing from 5 to 30 (repeat for an SPF of 50). The stuff wears off after a season's worth of launderings, so use a permanent marker to note the year of treatment inside the collars.
