Yes i am using evercoat lightweight to pack the FG as recommended by Rich from MTF. This is what he does to get a bigger bonding area. I bought some 3m 08115 bonding adhesive which is what rich uses as well.... Im not sure about it though. I feel like screw sunk in would be a little more permanent but i dunno lolNice, are you using the evercoat to pack the fiberglass pieces? What are you going to use for the adhesive? I plan to eventually get the side scoops.
Ive decided to go with hard lines as i dont want to risk cracking to feather it in. I am feathering from the door gap to the door thoughAs for the edges of your scoop, it looks like the scoop is very close to your rear flare. You'd probably have to blend those two edges together when feathering since they're so close. I always thought the blended in scoop looks better for that style, the Shelby style scoop looks good with hard lines.
