Default Bonding plastic to metal

OK what are your recommendations?

I need to bond some extruded plastic to aluminium. It's two locating lugs on the centre console of my car that have snapped off and basically needed to be bonded back on.

The 'weld' needs to be good as they hold the console trim down onto the console.

I have some 3M DP 8005 plastic epoxy bonding that the 3M site says can be used to bond most plastics to a metal including aluminium, but just wondered if you guys had any other bright ideas of what product to use.

TIA

I've been playing with Gorilla Glue this weekend quite impressive stuff TBH, take a while for the glue to take a firm hold though but it's fairly solid when it does.

Yeah I thought of that but I think I need more of an epoxy than an adhesive.

Friend of mine had some stuff, would bond pretty much anything together. Forget what it's called, but, have asked.

This stuff http://www.google.co.uk/imgres?imgur...oHQAg&tbm=isch it won't handle a LARGE amount of vibration but I have never come across anything that it hasn't held. It doesn't seem to matter what the material is, it just grips.

You can also leave it for a short time once applied to each side and then when you join the two bit's it holds in seconds.

P.s it's cheap too, the price not the quality.

Cheers Chris, I did wonder about that as I too have used it before with a lot of success, but not for a few years now. Will read up on it again.

Now I did read about this earlier and seems it might well do what I need. Thx.

My issue is that once this lot is back together it's a git to take apart so I wnat this to work first time.

With the one I recommend if it doesn't hold like LuckyWelshchap to a sheep with in a few seconds then pull it apart and clean it off.

sorry lucky

To be fair one or two of the German bits are not without their issues, but that is as much criticism as it's getting

This - been using it for years in RC models. Just remember to damp the surfaces with water to kick the glue. And wipe any excess (it will foam).

Once dry it will be seriously strong.

Seriously impressed with it so far, I glued steel drainage/guttering together and it's now hard as a brick! A bit messy but I wasn't being overly carefull with it.

Don't forget to abrade with emery cloth then degrease before applying the glue. I would use a two part epoxy like Hardman.

Just done a test fixing with DP8005 Plastic epoxy I already have and although the curing time is 24 hours after 2 hours I had to use both hands to break it off and that is without any surface preparation so think this will be the go.

In some cases a plastic epoxy can be too hard, car's are subjected to a lot of vibration and it can fracture the epoxy.

Yes, but DP8005 is designed specifically for environments where there is movement. I bought it to bond some Maybach parking sensor carriers to my Mercedes bumper. What I didn't know was whether it would bond sufficiently well to metal, but I think it does given today's experiment. We will see for sure when I bond the lugs back on later.
