Picture of Water Proof Pouches
This duct tape water proof pouch is sealed by doubled zip-lock bags under a quick release snap. Webbing on the back side allows for attachment to your life vest. Window cleaner helps make it possible.

You’ll need:
Duct tape
Window cleaner
Razor blade
Quick release snap
Reflective tape
Strait edge

Step 1: Set up

Picture of Set up
Find two zip lock bags in the size you want to use. I used 1 quart bags. Cut the bottom off of one of the bags. Place the intact bag into the bottomless bag. Adjust the bags so the zip locks are one above the other. The zip lock of the intact bag should be on bottom. See the pictures.

Spray your flat surface with window cleaner. Place the doubled bags on the wet surface and spray that as well. The window cleaner will give you some freedom in placing the tape. Don’t worry it will dry without effecting the performance of the tape.

Step 2: Duct tape strips

Cut a strip of duct tape long enough to cover the bag width wise. Lay it over the bag and squeegee out any air bubbles and excess fluid. I’m using a bondo plastic spatula but a credit card works well too.

Continue overlapping strips until the entire bag is covered. Next, apply a layer of strips vertically. When that’s done flip it over and do the same to the other side.

Apply cleaner as needed to keep it from sticking before you want it to.

Step 3: Trim

Picture of Trim
Using a razor blade along a strait edge remove the excess tape on the sides. Make sure to leave about a ¼ inch border around the zip-lock bag. You can overlay a third bag to help guide you.

Apply tape to the bottom and sides to cover the seams exposed from trimming. Also apply a single horizontal strip of tape over the zip-lock area to aid in pressing the zip-lock closed.

Wipe off any remaining window cleaner from the exterior of the pouch. Place a couple paper towels in it and let it dry over night. In the mean time make the adjusting strap.

I made one and it is awesome! Love taking it kayaking to hold my phone and other items. Instead of the clip I used Velcro as that is what I had avalible and it worked nicely! Thank you for the great idea!

what if someone steals your vest? then your national treasure map will be gone then your lost...hahahaha

I do like this btw, might work for something else, can't think of what else at the moment.
I'm thinking of using this to make an inexpensive "webbing" tactical vest / leg bag of sorts. For my needs, I would add in some reflective strips too.

Ok, how the heck did you learn that trick with the window cleaner? That is GENIUS!
Mrballeng (author)  mslaynie3 years ago
I used to work as a mechanic for a construction company. We would use window cleaner to apply large sticker logos on the doors of the company vehicles.

With out the "application fluid" we ran the risk of creasing or tearing the sticker while trying to put it in place.

The same kind of idea is used for tail light tinting.
...and window tinting.
Ahhh, ok, that makes sense!! I've often wondered about those auto decals! It's always seemed like they would be super-easy to mess up, especially if you're as clumsy as I aml

This is one of the best looking duct tape projects I have seen.
Mrballeng (author)  ehudwill3 years ago
Cool Thanks!
Now this is a cool idea! Makes me want to make this for some other type of application which if I ever find my camera I will make some things for camping. My youngest daughter and I are giong camping in a few weeks, might be just the thing to do on the downtime before bed. Can't believe I forgot about the windex trick. Once again thanks for the insperation Mrballeng!

Thanks. Hope you have a good time camping.

Why not just fold the inner bag and tape it instead of cutting a perfectly good inner layer?
Mrballeng (author)  echodawg3 years ago
Good thinking.

I love this! My 2 boys are Boy Scouts & this pouch would work GREAT for their canoe trips! Also, several of the boys in the troop love to make things with duct tape, so they'll love this too!
And thank you for reminding me about the window cleaner trick. I'd forgotten until I asked you about it, but now I remember that when they 1st came out with the tinted window film you could put on your car yourself (ages ago), we had to spray the window with window cleaner before applying the film, so we could place it right before it stuck permanantly. I'd totally forgotten about it & am so glad you reminded me, because I hadn't thought about using it with duct tape & a couple of months ago I bought a case of 8x11 sheets of duct tape for my boys to make things with - this tip will sure help!
