I bought a Phase3 F-16 and would like to cover and paint it. Everything I read about covering these foamies seems to focus on silk and WBPU resins. I have never used this technique, but I am very satisfied with the results I get from using half ounce fibreglass and Z-Poxy finishing resin. This stuff is easy to sand and gives a smooth finish. Is there a benefit to using silk and WBPU over fibreglass and finishing resin? Has finishing resin been used before with poor results?
