Are you using black foam or gray? Ive always done all of my padding first. I usually pad the top of my gunwhales with 9mm (really helps the elbows when getting back on) then the tray, then the top and sides of my footholds. I’ll turf the sides then the front, and lastly the tray. As long as you tuck it in tight against the tray foam, and then tuck the turf up tight against the sides, Ive never had a problem with it ever showing bare fiberglass when standing in the tray. I use 26mm black foam on bottom
