I'm in the process of doing a so called non deseriable car [1973 charger/318 car] and we are useing duraglass in our bodywork.I did cut out the rust and patch with new metal [GMC TRUCK BEDSIDE, fileing cabinet metal] then duraglass to level/smooth then evercoat filler to finish,eventually i'll be spraying the polyester filler as stated before, then blocking it to smooth finish prior to painting. We are not building a show car just an acceptable cruiser for my son.
