I'm getting a BSE for my 8900, but I've heard that you have to make your own solution, whereas the InvisibleSHIELD comes with the misting spray.

Do you recommend I buy & use the InvisibleSHIELD misting spray ($2.49) or can I empty it out, and refill it with a solution recommended by BSE?

Or should I just scrap all that and just follow the instructions per BSE?

P.S. It's a full body shield, so I thought the spray would make the process easier.

Hope you have better luck with this than I did.
Finally gave up after screwing with the solution and little pieces of sticky plastic which instantly get fingerprints (in spite of my best efforts...yes I read the instructions).
I quickly became convinced that this product would be more effective at making my Pearl Flip look like crap than anything else...
Like I said...good luck with it! I'm waiting for my leather case.
