I have been working on the kit car style deckild vent that I received from Driven Visions. My deckild is cut and the vent is trimmed and ready for bonding. I have a question for all you bodywork guys out there: Do you think it would be better to glue the vent to my decklid using Gorilla Glue or SMC Panel Adhesive? The gorilla glue seems very promising and I dont want to have this vent pop back out and crack over time. I will be posting a build thread shortly. Any advice will be greatly appreciated. Thanks.

I think Gorilla glue is water soluable - so no - not good. but, not sure

I would use the SMC Panel Adhesive, that is what it was designed for and is very strong for holding panels in place. After the adhesive sets you will break either the original Fiero panel or your add-on penel before the adhesive would break. I used screws to hold the panel in place while the adhesive set. I gave it 24 hours even thou it doesn't take near that long for the adhesive to work.

Gorilla glue I've seen used in Concrete applications for cracks, etc. I do not know how it would react with Fiero body panels and add-ons.

So Far, I have used Gorilla glue to repair some of the dash parts, glues a piece of plexi to the stereo surround, no more stereo , and used it to repair a plastic airfilter housing. No problems whatsoever!

If it could be used on the SMC panels, that would be Fantastic!

According to thier website, Gorlia Glue is 100% waterproof, will bond almost anything to almost anything, forever ,except for some plastics, which might be dificult to cure. Note, it doesn't say it won't glue the "certain" plastics, it just might be difficult...

I am tempted to go and try to glue something on to my junk/test hood...


Edit to add: I just sent an email to the Gorilla Glue people, will let you all know.

A couple of points. Corvettes are assembled with SMC adhesive from the factory. I did a lot of RV Class A motorhomes and they use a ton of Gorilla Glue (we called it Gorilla Snot). They even use it to mount all the hinges on outside storage doors, hoods, engine bay covers, etc. Eveything almost on the exterior of them is Gorilla glued or pop riveted on.

Just more input, My dogs plastic water disk was leaking and for the heck of it I used Gorilla Glue to seal it.
I routered out the crack to widen it and then applied the glue so it was a clean surface.

Lasted about two weeks and started to leak, The water did indeed seem to weaken it after being submerged for that lenght of time. It was not as hard as it was after drying for two days.

Not scientific, just an what happened.

So, are you saying it can be used?

Hello,

I am wondering if there has been any testing in using Gorilla Glue to bond fiberglass materials, i.e.: RIM, RRIM, or SMC?

Those materials are found on a lot of cars today...


Thanks,
Don

THE RESPONSE:

Dear Don,



Gorilla Glue can be used on fiberglass. If you need to, we recommend roughing up, or sanding the surface of the fiberglass first, to give the glue something to adhere to.

Not the most comprehinsive of answers, but promising nonetheless

There are a few more issues to consider. First if the Gorilla glue is on the paint surface in any amount is it paintable? I would hate for you guys to use this and all of a sudden your paint starts lifting. That would be a mess I would do without. Secondly, sandibilty, how well does this stuff sand if you get it on the paint surface?

Personally, I would spend the extra amount of money and use the SMC be sure you won't have a problem, but thats me.

I agree completely! however, the http://www.gorillaglue.com/ website answers a lot fo these questions. Mostly in favor of it being easy to sand, etc...

I used SMC Panel Adhesive on my scoop and it worked great. Why use something different? If you go to body shops, they'll not be using Gorilla Glue. You can bet they'll have some form of SMC around the shop.

Wow, thanks for all the responses guys! I know how strong the gorilla glue is so I was just thinking hypothetically if I used it it may be stronger than the SMC. But I know that SMC adhesive is used specifically for this application so I will be using the SMC instead of the gorilla glue. I just wanted to see if anyone else thought of using gorilla glue for this type of work.

Well, based on my research, I am still going to give it a try.

Of course it will be on a test hood!

How do you know if something is going to work or not, if you don't give it a try?
Just because it wasn't originally designed or intended for a specific purpose does not mean it won't work.

If we all assumed that, we would still be riding a horse to work! Not to even mention the idea of putting a 3800/Northstar/etc... in to a freakin Fiero

I use a lot of Gorilla Glue - it's waterproof after it dries completely. The key is "after it dries completely" - depending on temperature and humidity that may be a couple of days. It sands well and seems to accept various paints with no problem. It's one of the best adhesives around for sticking various broken Fiero plastics back together, and I've used it's "foams as it sets" characteristics to re-foam broken dash corners; works great.

That being said, if I wanted to bond a scoop to the decklid I'd reach for the SMC panel adhesive. If you're expecting to bond panels with a thin glue line and sand it down to perfection then Gorilla Glue isn't what you want. It makes a thicker glue line and the set glue is somewhat foamy...

I have used Gorilla glue when I glued the aluminum strips on my 3800sc valve covers. I will say this stuff is there forever. I have used it to glue the magnets back in place on the power window motor. Us far as it being water soluble I not so sure. If you get this stuff on your had for jus a second you darn near have to scrap it off. Being careful when using it on interior parts, it expands and you cant remove the excess.
Some friends of mine fly RC planes and have always used a two part epoxy for repair until they found this stuff.

I used Gorilla Glue on my coffee thermos and it didn't last. I assume it was the part about putting it in the dishwasher. The combination of heat and water must have taken its toll.

Otherwise, I like the glue and use it a on a lot of stuff. I wouldn't use it for body work though (what will happen 2 years from now?)
