As I've decided to make my JF Caddy XLR a wide body I figure I'd better get some insight from the experts, as I've done resin repair but not modifications to a resin body. Can anyone tell me what is best to use as a body filler on a resin model? I want to make a skeleton framework using styrene for the flares and then use filler for the final product. Is Bondo okay? Any help/input would be appreciated.
