Hello I have a 54 Chevy Truck. In the begining stages of restoration. My truck has rust on the cabcorners-cowl areas. Also at the bottom of both doors. I know there is alot of work to be done. Would like to hear from experience what is the best route to take. If I sandblast the metal should have a rough finish-do I sand afterblasting or prime and then sand? Just want to let everyone know you will probably see lots of ?'s from me. Thanks RHuddle56
