Mr. Bruce knows his stuff. Need to bevel grind or dish grind the areas deep enough, front and back, to lay in about 4 layers min., of mat and resin, rolling each layer out to compress it and remove excess resin. Cut each strip a little wider than the last so that it fills up the dished area in layers with the last slightly overlapping the original, full thickness fiberglass right under the gel coat. Then grind and sand to contour, fill any minor areas or pinholes with filler, and prime with a couple coats of high build polyester filler like SlickSand for final blocking down. That’s the only way to fully hide the splice joints in the finished paint.
