Secondly, EkoFill will fill minor imperfections and sand to a smooth, level finish. EkoFill can be used to fill and sand on fabric as well as composite. Thirdly, EkoFill as a primer provides an excellent surface for paint to adhere to. When properly sanded and cleaned, Stewart Systems EkoPoly Premium will bond to the EkoFill with extreme adhesion. EkoFill may be used on fabric, composite, wood, vinyl and many plastics. It is, however, not recommended for application on bare metal as it does not have corrosion inhibiting properties.
Because EkoFill does not contain any metallic components, it will not interfere with radio reception or transmission allowing antennas to be mounted under fabric. The natural color of EkoFill is charcoal and therefore cannot be tinted to any other color.
