Nice tip GP, I done close to the the same only with cardboard.
It's still a bitch to clean compared to white paint though especially if you like to foliar feed.

First off..what in the world is this "Panda" stuff? After racking my brain a bit, I am assuming it is a retail or slang name for black backed white poly sheet?
Anyways, the bottom line is if you use sheet goods as reflector material, it needs to be perfectly flat, or the crinkled spots will concentrate light onto certain spots of your grow, and cause hot-spots where your plants will be scalded by the magnified light.
I use flat white paint because it is alomost as good as the best, its super easy and cheap to apply, and if it gets damaged, just slap on a new coat.
What extra efficency gained by using something more substantial, will not be noticed at the bottom line(at harvest) in my opinion. There are way better places to put your time, effort and money.

This is true-titanium oxide. Also, the good stuff like "SNOROOF" or simillar is an elastomer paint (it strecthes and does nto crack), is totally waterproof. Seals gaps. Wipes well.
Mylar-hassles with less benifit.
Can't go wrong witht he roof paint.

Thank you all for contributing more to my thread I have had some interseting responses. Over all I am going with guineapig's advice and making a reflective wall that is taunt so I dont loose any more light.

Another thing is those mylar windshield heat deflectors. Those work. I've seen them in many a growbox.
Great thinking buckwheat. Definately gonna use that instead of white paint for my cab.

To add to GP's advice, I've done the same thing, only used heavier-duty boards to attach it to (think of that wood-grain paneling stuff). But, I eventually got sick of mylar, PITA stuff. Now, I use paint on pre-existing walls or, if I need to create a wall, there is a white panel board (4'x8') that works extremely well.
If you're still wanting to do mylar, keep an eye out for emergency blankets or mylar gift wrap. Cheap, and darn near as effective as mylar you buy from the hydro store. Works when the $$$ is low.
Peace...
EDIT: Foylon? Yuck!!!! I used that stuff once, until I noticed little silvery pieces of foylon EVERYWHERE, including the buds! Never again!

Why doesnt glossy white reflect more light then flat white since its so shiny?

flat white paint is the best mylar creates heat spots. and mylar gets dirty real fast and looses its affectivness. if u realy need a good reflective board go to lowes or home depot and get a sheet of tile board for a shower with the white surface it BLINGS and its light and cheap u can cut it in 4x4 sheets to fit ur need 12.95 is the cost
FeelingHazy-Just like with a crinkled piece of mylar, gloss paint reflects light unevenly, it tends to reflect light directly back, insted of scattering it(notice it shines light back at you, like a mirror).
Flat white reflects the light more evenly, I guess because it is flat? LOL!

Lemonade: Wait for it to degrade. I used it for a few grows, was sold on it because of the durability, and the ability to use it to eliminate wasted light in the corners. After a few months, it started to degrade and the reflective started "flecking" on in little pieces. Any reflective that could end up in your buds is a waste of time IMHO. So, I won't ever use that stuff again. Your mileage may vary. 
BudsByKano, I think that's exactly what I'm talking about. Pretty durable, and cheap! I use the 4X8 sheet to make an 8' long 4' tall reflective wall that I can easily move out of the way for maintenance, etc... I'll post a pic later and show you what I mean. I used a couple of pieces of wood to hold it up, and it works great! Stonervation (stoner innovation) is a great thing! :wink:

I found this stuff to be lighter and pretty sturdy compared to a lot of backer materials for mylar. I use double sided tape in 6" of the corners and that makes it easy to replace the old mylar. Comes in 4x8 foot pieces in a few different thicknesses and cuts to size with a razor. Available at any Home Depot or Lowes with a home building materials section.
