^^Hey wait dont try the epoxy(assuming its the whitesh or transperent thing that when dries up is rock hard) as it will render it unrepairable for future for correct operations like reheating with paste or reballing it.
And how the hell heating with welding iron came to your mind??? That scared me as hell
you better try off the spring thing thats way better then yor current ideas.
Removing or ill fitting sheild is no offence
