hi everyone,
Under our dash it always has a draft. don't know if this is on any other post but we took big huge garbage bags put blown insulation in them took as much air out of them sealed it with duck tap stuffed it under. Bought some material put it on spring curtain rod in front of bags to make it look nice, no more draft. I was great! Last year we tried the rolled silver stuff at lowes but we couldnt manover over things.
