Whitewall tires for sidewall Dynamo?
 

I have an Electra Amsterdam with a sidewall Dynamo which I love. I'm looking to find a set of whitewall tires for it, but I'm having a hard time finding any that have the friction strip for a sidewall Dynamo. Does anyone have any recommendations?

I've also wondered whether it might be possible to get any tire and use some of the various spray-on traction materials available, such as this from Home Depot: Rust-Oleum EpoxyShield 12 oz. Anti-Slip Aerosol Spray-268652 - The Home Depot

I'm not looking to go to a Dynamo hub for what it's worth, so no need for that recommendation. ;)
