Any of you ever use heavy duty aluminum foil for shielding a strat cavity and underside of a pickguard? I'm too big of a cheapskate to buy a roll of copper shielding from a place like GFS. I have used that sticky foil tape for HVAC ducts that you can buy at Home Depot - but the fact that its thick and sticky as heck makes me want to swear in front of my kids when I'm using it! I want to try using a roll of heavy duty foil I'll buy at the supermarket. Has anyone else done that? If yes, what sort of glue did you use?
