The truth and the light..

So my current cab took a while to get light proof but the problem is i have to shut the doors just right to make sure its light proof, other problem is if anybody walked up to my cab and tried to open it light would come out the cab there for ruining any stealthness i had...

So here is my idea, Essentially put up another door behind the cab door as kind of a sealer. I was thinking about getting material that people use to for grow tents and using that.. Anyone have any idea where to get the material? Other question i had was how would i go about adding a zipper to the material so its easy to get in and out?

Some advice would greatly be appreciated

how about making some black curtains to go in front of door that can be slid back and forth.

When I cared about that I used a black piece of viscane or plastic and made the curtain inside the cab and when the doors close the curtain was inside and sealing the edges as I had cut it a little bogger then the opening and attached across the top. and you can just push it out of the way when needed. Or you can run Gorilla Black tape doen the inside edges of the doors---creating a gasket from the inside and if you cut that same plastic to hang in front of the door break you should have minimal light I used weather stripping too.

The easiest way or at least most effective way i found & have used on my stealth box is a singled sided foam like tape. it has 1 sticky side to apply to the edge & the other side is urethane foam/vinyl. the link below has a set of examples of what you could use.
