Interesting. My biggest complaint with the Banana Boat spray has been that it always leaves me feeling greasy. That and after I spray it on, I feel like it still needed to be rubbed in and then leaves my hands all slippery.
Now, if I am using one of the sprays, I only use the Coppertone Continuous spray. It goes on nicely and evenly and I don't have to rub it in. So no greasy hands either. The only thing that I find is that I want to make sure to shower it off at the end of the day (which I would do anyways after a day in the parks) to make sure to get it off. But it works great and I haven't had any sunburn problems with it either. We have used the Kids one SPF30, and the Babies one SPF50 and both have been great!
For our faces though, I have started to use a stick also. Doesn't seem to move around when we get sweaty and the kids don't end up getting it in their faces as easily. For sticks, I use a Coppertone Babies stick or the Blanket Babies one and both have worked well for us.
We got lucky too. This year BzzAgent happened to send out some of the Coppertone spray as one of their campaigns and we got to try out the new one they have for kids that comes out colored so you know where it has been sprayed on, then goes colorless. Been great to help teach DS to make sure that he is fully covered with his sunscreen.
