Sidewall Plastics from the store here

[odin]

How do everyone?

Can anyone tell me if the sidewall sheets sold here at the store are flame treated on one side?

A core client of ours bought some wide sheets for their ski cores and I am getting ready to attach them. The plastic sheets look the same as any we have gotten from Crown which come flame treated and sanded on one side.

The sheets I have here are sanded on one side for certain, but I am unsure as to if they are pre-flame treated.

I figure it's best to know if I have to flame these up or not before I get to gluing 'em on : )

Thanks for the help
