I've gotten bad rashes from my surfboard, and heard of this stuff called bodyglide that will prevent the rash...
what is it, and does it work?

It is an anti-chafing lotion that is more so used with runners & swimmers. l use the stuff when l go on long runs/marathons.

l would not recommend it for surfing, however. You need some sort of friction between u & ur board, or else u will constantly slip & slide across the board while trying to paddle, & that is not good.

Use of a rash guard or wetsuit will give u much better results. It eliminates rashes by blocking the skin-board wax contact from happening in the first place, & make sure it fits a little tight so it will also prevent armpit rashes from happening also. While preventing the rashes, it also does not eliminate the board-user friction needed while paddling. So it is a win-win :)

Rash guard is probably even a cheaper alternative in the long run. A new bottle of bodyglide costs another $7 when u run out. A rash guard will last u years & u can get one for around 20 bucks.

l would just buy a rashguard or even a wetsuit jacket. To get rid of a rash l use some rash cream stuff. You can buy that at your local drug store.
