From what iver read in numerous sources is that buttcats have thin hulls and therefore they need Pu foam to strenghten the structure. But if you add 2 layers of glass to the hull then you shoul be able to use sondor. Make sure you have enough stringers and bulkheads. 18mm nidacore with 2 layers each side is more then enough for stringers, bulkheads and the floor. Tip to save some resin when working with the nidacore is to take a roller and resin to seal the fabric first. Then when its sticky or hard you start adding the layers. Otherwise the resin will flow out of the glass and into the cavities while working over the glass
