Re: Methods to Adhere KING StarBoard to Thin-wall Laminated Surfaces

I've found that trying to use adhesives on KING StarBoard is about the same as trying to glue Teflon. Many complain that the adhesione can be inconsistent. I'd opt for a G10 backer or another material for years of trouble free bonding.
