Re-attaching badges to bodywork?

Hi guys,

Just wondered if anyone has any experience of the correct glue to re-attach badges to the bodywork?

I have a rectangular "cavalier coachman" metal badge that I need to re-attach after dealing with rust behind its position on the rear door.

Toolstation has more than a dozen variations of "sticks like shit" "hard as nails" etc, then there's gorilla glue, good old araldite etc.

Is there a particular type of adhesive that is best for metal to metal (actually the back of the badge is covered in layers of glue which won't come off) that won't fall off or give up after a bit of rain/cold?

Thanks
Jim

705 clear silicone off eBay (50ml tube for about £1.50). Works like any silicone but is stable at higher temperatures as well as being water resistant.

When used as a thin film adhesive at about 20C ambient temperature the initial cure is quite quick (from exposed edges inwards) but allow 4+ hour for full cure before picking at a badge to check the bond. Cured 705 can be cut through with a thin blade or dental floss.

Try xylene base paint thinners on the old adhesive: if the adhesive softens then it will come off, eventually. So will any paint or similar polymer coating on the face of the badge so take care ...

Scrub off solid cured adhesive on aluminium oxide paper laid on a flat surface.
