aluminum paint?

OK its made by Black Jack and it says its a high reflectance. it says you can use it for large gas tanks outside for sheds silos and fences. since its paint it cant wrinkle so it cant make hot spots does any one think that it can be used to line the inside of a grow room

here's a link... ( McCoy's Online Catalog - Black Jack Aluminum Paint - 1 Gal ) check it out

Anyone have any ideas if this would work?

I cant believe that no one has said any thing about this!!!

dont think so, your going for Flat white when it comes to reflective paint.

I find that interesting.... especially since that seems to be the opinion of most people I see post here. However, I do remember one post from a person who works in the paint industry and he said flat paint is not the most reflective, but gloss paints are.

Additionally... I found this: Untitled Document

from the link:

[FONT=Verdana, Arial, Helvetica, sans-serif]Gloss Paint[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]Gloss paints, sometimes called high gloss finishes, have a highly reflective appearance.


[/FONT][FONT=Verdana, Arial, Helvetica, sans-serif]Flat Paint[/FONT]
[FONT=Verdana, Arial, Helvetica, sans-serif]Flat paints have a non-reflective, matte finish [/FONT]



Pretty much every paint site I checked says that Gloss is more reflective then Flat.... so where did everyone come up with the notion that Flat paint reflects more light? Perhaps I'm just interpreting it wrong????

Personally when I re-paint my grow room I'm going to use a White gloss paint.... if for no other reason then Gloss paints allow for better cleaning and wiping down... which is very important in a grow room

I think gloss paint produces hotspots I may be wrong, I've just always heard Flat white is the way to go

One of my other hobbies is projectors, and in the world of projectors there are two types of screens. FLAT WHITE, and Aluminum (often referred to as silver screens)

The right aluminum paint applied properly to the right surface can yield a gain of up to 14x and a flat white screen can yield a gain of 1x. They get 14x by utilizing the way aluminum hotspots and most all aluminum screens are curved to focus the light back to a narrow viewing cone. It's not really 14x the light reflectivity, it's just focused 14x more narrow.

In theory aluminum paint wins as being more reflective, but it's very hard to get the right surface and texture to be more reflective than white but not hotspot. And you can get that wrong and you have a gain of less than 1, less than flat white. Flat white is the easiest and most forgiving and on any surface with any texture it's still a gain of 1.

So... If you do aluminum do FLAT aluminum paint and make sure to spray it on a good smooth surface that can't wrinkle but give an aluminum finish that does have minute texture like a dry spray and then grow with it and give us the results. Do not use a gloss of white or aluminum the gain IS lower than flat of either, way lower.

I prefer Behr Ultra Pure White for most of my projector screens but I have used aluminum screens also to make them reflect more and make projectors daylight viewable. There is a flat aluminum spray paint available from Rustoleum with the proper characteristics for an aluminun screen, one right one, and there are 1000 aluminum paints that are wrong and worse than flat white.

now were talkin thanx
