Afternoon all,

I'm very shortly going to need an epoxy adhesive or similar to bond my door skins to the frames and some mounting brackets to various other parts of the car.

I'm not too worried about some of the areas as I’ll be able to reinforce with more c/f and resin etc. but on the doors I only have a very small surface area and have no idea what to use. I need something pretty structural with some gap filling qualities but cure time isn't that critical.

If anybody has any advice or suggestions it would be appreciated

Thanks

Tiger seal is good stuff.

Maybe try emailing carbon weezel or whoever supplied your door skins and see what suggestions they have

We use redux from Hexcel at work, it's the bomb... but it's bloomin dear!

Tiger seal is great and i've used it to fit bodykits etc, but not sure about bonding without mechanical fitting support on something like a doorskin! really don't want it flying off lol

Oh, and the door skins were supplied in my shed

Not too worried about the cost (within reason) if it'll do the job. I'll look into it though before I commit too much lol

Cheers guys

When you've got the old door skin off why not just weld a strip of metal around the inside of the frame to make the lip twice as wide? You'd be effectively doubleing the surface area to bond to. Tiger seal is only about £10 per tube so wouldn't be expensive to do 2 doors.

I used sikaflex for my roof and that hasn't moved I found if you put it on too thick it doesn't dry in the centre so it moves,it it on thin and you could glue your mini to the roof

Wurth bond and seal gets my vote, it'll stick anything to anything and won't come apart in a hurry. It's a seam sealer too, which is what I actually bought it for.

I'm not sure sikaflex or tiger will do the job as I have mk1 hinges and although a lot of weight has been stripped from the doors and it's running lexan windows I still wouldn't like to rely on silicone as such; I don't think the shear strength is that good?

I forgot about the external hinges in post 1; my bad

My door handles are also different and I have to pull them rather than press a button so more pull forces acting on the skin

Stumbled accross this earlier Loctite Hysol 9430, but contacting Loctite for suggestions and recommendations too. Anybody ever used it?

Brams96 - door flanges already had a bit of widening done but great idea

We use Hysol on Civil Aircraft and if left to cure properly is very very good.You will need to key the surface and obviously make sure its grease and oil free.

Another product we used to use was made by Goodrich but i cannot find the spec or part number. It was a two part adhesive again much like the Hysol products and when applied correctly you had to use a chisel and large hammer to split it.

[sonikk4]

One of the Hysol products we use is Hysol EC3535.Two part adhesive with good shear qualities. I think if i was you select your adhesive then make yourself up a test piece to hang a 10kg weight off. You could then if using a suitable method to hang the weight lift the weight a few inches or so then release it to see if the test piece fails. If it does not then happy days use it on the Mini.

[Brams96]

If your worried about the shear strength you could always put in some strengthening plates behind where the hinge holes will be to take some of the extra weight.
Something like this:
