I have sealed my restoration body with Eastwood’s DTM epoxy primer. Two questions for the experts. First, do I need to topcoat it? Where the bottom of the rocker panels meets the chassis, it’s not visible. I loaded it on pretty heavy and won’y waste the topcoat paint if it will protect and seal as is. Secondly, there are some areas where I’m using acrylic enamel over it. Do I need to sand or scuff it before I topcoat. These are obscure areas that don’t need a nice finish. Thanks in advance for a reply…. Jeff
