Very little color intensity is lost during projection. BUBBLE BOARD panels may be joined with clear tape. Panels can be painted with most conventional scene paints. Two panels may be laminated together with Roscobond. BUBBLE BOARD is available in 3xl0 foot panels, 1/4", 1/2", 3/4" and I" thicknesses. Send for a free sample and additional information.
