I spent a lot of tim getting the filler work blocked pretty smooth so hopefully the primer blocking will go well. I put on three good coats of high build primer so there should be enough on there to get it nice and smooth.
One thing that disturbs me is the rough finish on the inside of the side panels. I know no one will see it, but I just don't like rough finish of the backside of the fiberglass. So I thought I'd try an experiment. I ground down the surface w/ a flap wheel. Not too much, just to knock off the high spots and the fiberglass pattern. Then I sprayed a few heavy coats of slick sand. I let that cure and see how it sands and if it's comes out smooth enough, I'll paint the backsides bodycolor.
