Glue removal from metal 

I used Gorilla Glue to repair a small piece that was broken from a magnesium cover.  I realized too late that Gorilla Glue is probably not going to withstand a chemical bath or 400 degrees F baking and also will not conduct electricity.

I plan to break the piece off again and remove the glue.  would it be possible to burn the glue off as scraping it would be impossible.  Would indistrial paint remover sofen it up?  Any other chemicals I could use to dissolve it?

Re: Glue removal from metal 

Just wanted to report back that I contacted Gorilla and they put me in touch with thier Chemist who was extremly helpfull.

She indicated that Gorilla Glue begins to lose adhesion at about 215F and when she realized that the magnesium can withstand up to 1,200F she said I could simply burn the glue off as its an organic material.

So, I'm going to bake my magnesium piece at 250F - 300F and remove the broken piece, then torch the Gorilla Glue off.  Ultimately, I am going to weld the piece back on as I need it to be exactly the same... heat resistant over 550F, conduct electricity, etc...
