I just purchased a GT deck so I can experiment with a mustang scoop without damaging my original. I have a 79 style scoop with 5 bolts, I have already drilled and did a dry fit and it looks great. Now for the questions, first of all I have never done anything like this before so please be specific, I have done quite a bit of searching and reading on the forum so I'm aware of the SMC panel adhesive that is needed, I will probably use the everclear so I dont need to spend the extra money on the applicator that will only be used once. My question is after using the adhesive do I use bondo to round the seam or can the everclear be used? Any other tips or pointers would be greatly appreciated, thanks guys
When I added a Mustang scoop (a long time ago - 90's), I cut a hole and then simply bolted it on with the 5 bolts and it sat very flush with the deck. I had it for a long time like that with no problems whatsoever and it looked factory to me. Maybe now they're doing it differently / better?
Oh, and that's a nice Fiero you have!

I swear by it and many others will tel you "3M 8115" panel adhesive is the best. You will wreck the car and smash the hood, the scoop will not come off. I have used it for everything from bonding wood back to my John Deer tractor hood having cracked badly and put it back together. Some shops carry it like by me a Body supply place has it. I have found it at times cheaper on line. Rick B
If you want an molded in look you will need a full decklid repaint ... alot of sanding ...
Good luck on your build ... post lots of pics
I'm figuring alot of sanding in my future. I will have it sprayed by a professional for sure but I'm looking forward to doing the customization myself. I just want to do the right job with the correct material.
Fierojp, what model year Mustang did your scoop come from? Looks very nice!
I remember it being from an early 80's Mudstain that I came across in a junkyard. I don't know if guys are using different ones now, but the one I had fit flush enough that I didn't think it was worth the trouble to fill in the seam. A great mod for the Fiero - looks great and functional!
The other thing I did with that car was put rearward facing Trans Am vents on the front to allow some of the trapped air out of there. Has anyone ever verified if vents on the front hood help reduce front end lift at high speed? I never had a wind tunnel!

I definitely would NOT use everclear, you’ll be way too drunk to do decent body work.

I used a twin tube panel adhesive to bond my scoop to my decklid, then used the evercoat to blend it in. Evercoat vett panel adhesive is basically bondo for fiberglass so use that and NOT regular bondo. One thing to note, evercoat is harder to sand than bondo so don't overdo it.

Wow i like that. Also interested to know if it helps reduce lift.

Heck, if it keeps the headlights from popping up at 105mph then it is worth it and is probably reducing drag. Have you driven past 105 - do your headlight covers still pop up?

Waynes Speed Shop & Auto body South Amboy. You might want to check out the speed shop if you haven't already. I finally got around to installing it today, not washed yet so disregard the dust but the paint looks like glass and where he molded the scoop in looks perfect like it was from the factory.
Id have wholeheartedly agreed with others to just bolt it on and be done. Never would have a problem. With it molded on, you have varying thickness on the trunk lid. When the engine gets hot, it will contract and expand at all different rates. You may not have a problem, but Ill put bets on it cracking somewhere within a year or two. Usually the whole blend cracks all the way around. I put a 6 pac hood scoop on my Dodge. Just bolted it on and no issue at all in 6 years. Looks factory too. If you dont want just panel on panel, you could put a gasket around it....like the wing has.
