Let's be real – no one gets giddy about aluminum foil tape. It's like the socks of the home repair world: necessary, but about as exciting as doing taxes. BUT, let me sing the praises of 3M Aluminum Foil Tape 3381, because this ain't your bargain-bin tape, folks. It's got superpowers I never knew aluminum foil could possess ...Why you NEED this tape in your life:HVAC's New Best Friend: Leaky ducts are the air-conditioning world's villain. This tape? It's the superhero! Seals those gaps like nobody's business, saving you on energy bills and the shivers in winter. Who knew some shiny tape could have a bigger financial impact than your stockbroker?The DIY MacGyver: Got a rattle in your car? Wobbly furniture? Hole in your kid's inflatable unicorn pool? Patch it with this tape. It sticks to practically anything, and its durability defies logic. Now if only it could make me handy enough to actually handle bigger home improvement projects...A Cold Weather Warrior: The description says "cold weather," but honestly, this tape is tough as nails year-round. Rain, sleet, heat wave – it doesn't budge. Mother Nature might as well take a coffee break, 'cause this tape won't let her ruin your repairs.Romance Revitalizer? (Seriously, hear me out!): Spouse complaining about squeaky cabinets? A "strategically" placed strip of this tape quiets that hinge better than flowers. Now, THAT'S relationship-saving sorcery right there. Disclaimer: Might not fix ALL domestic disputes.Bonus: Zombie Apocalypse Prep: I mean, have you SEEN the strength of this tape? A makeshift shelter, a weapon patch-up... This tape's versatility could buy you precious time against the undead. Look, when's the last time duct tape did that?Okay, maybe I'm overselling it a tad, but you get the point. This tape is surprisingly impressive. It's made my DIY attempts less disastrous, kept my house's temperature regulated, and might even win me brownie points with the spouse. Now, where did I put that wobbly chair...

Used this stuff to seal up some air leaks around the house HVAC system. Since I had so much left over I also used it to partially seal up some of the radiator opening on my car to get a little better aerodynamics and then also seal up the area around the radiator so anything that goes through the front grill has to go to the radiator and not bypass it.Multiple 80-100mph 4 hour road trips and this stuff is still hanging on just fine. whatever kind of stick goop they put in on this tape is going to take an act of god to get it off my car if that time ever comes, but till then this stuff is doing exactly what it's supposed to.

This 3M high temperature metal tape is very good tape if you want to get the job done right. Great for window air conditioning or for duck work central air conditioning/ heat

This is useful to patch any pinholes in duct tubes and can be used to reinforce the ends of duct tubing under where you will use clamps. Take care when unwinding from spool to avoid bending/kinking.

This has great adhesive qualities. It stays in place. Tha backing peels off easily.

Used this to attach insulation and skirting to my rv.Holds well!Comes off with no mess.

Used this along with insulation wrap, as others did, to wrap the output hose of a portable air conditioner. Until I did this, the device was pretty much useless because the hose radiated so much heat that it negated the effect of the air conditioner.Fastened the insulation in-place with this tape. Working just great! NOW the air conditioner actually COOLS the space!I did not rate "easy to remove" because it's not intended to be removed easily. It can probably be removed fairly easily however, depending upon what you stick it to, but I didn't rate this.
