67-69 Anvil Auto Carbon Fiber Door Skins install

[FireEagle]

Hi everyone,

I am new to this forum;

I was wondering what type of "glue"/ sealant is the best one in the market in order to bond carbon fiber to steel? I just had a pair of these pricey Anvil carbon skins doors delivered to my door am looking for any type of advice on this method of bonding together these two very different materials.

Also what's the effectiveness and longevity of doing this when compared to welding?

Any help is greatly appreciated as my body shop never did this job before and I am really trying to gather the best I can to avoid ruining two brand new doors of my 69 RS Camaro.

Thank you!

I would say call Anvil. Im sure they're have a recommendation.

Just a thought, I'm thinking that 3M #8115 panel adhesive would work. It's what body shops use to glue body panels on instead of welding on some applications.

I've used 8115 for fiberglass skins before. Just rough up the steel mounting surfaces with 40 to 80 grit & completely cover them to prevent rust. Also predetermine a clamping method & don't overtighten any clamps to the point of warping the skin, which could remain permanent after the glue dries.
Don't be scared of using glues, much new car construction is put together this way. Heating to over 400 degrees is the only way besides cutting to make a properly done panel adhesive come loose.
The lower cost smart brand panel adhesive from finishmaster stores seems to be just as strong. on a c-7 rear conversion I started on last year, used it to glue 7 separate sections of fiberglass material to a steel frame to make my own lower bumper. At worst I could see a little ghost shadowing at the joints once painted spi gloss black, but being at at an intersecting angle anyways, such as where a door skin meets the door, it'll likely never show.

Thanks guys, for all the helpful replies. I'm new when it comes to to this exotic stuff. lol.. I bought a ton of carbon fiber and aluminum for this car so only the floors, roof and rockers are stock at this point on my build.

Also, is it better to find a way to clamp the skin to the door shell and use weights on top at the same time? What would work best?

I think your going about it right, but like stated above, go easy on the clamping for several reasons. You don't want to warp any steel, break the fiberglass, or squeeze too much adhesive out. You'll be ok just don't over do it.

You only need to hold the skin in place till the adhesive starts to set & not have it move . If doing with the door panels laying flat on a bench, you could probably just tape it in place. Black gorilla duct tape works well for stuff like this. large spring clamps could also be used , rather than ones you squeeze or twist tight.

Also as I said before, predetermine (&test) how you're gonna clamp it before you break out the glue since you're new to this. Don't won't to struggle with figuring clamping or doing any extra reaching for clamps on you're first try of using panel adhesive.
On a previous tailgate skin project I also ran a bead of 8115 over the metal edge of the framing & onto the inside of the skin after setting time & smoothed over with finger for an initial bodyworking of the area..
