Be that as it may, there will still areas, that separated the plywood when I pulled it off of the aluminum. One of those is visible below.
Although, there wasn't a lot of paint that bled through, it was not easy pulling the plywood off.

If you want to do something, you will find a way.
If you don't, you will find an excuse.

So, now it's time to go stand on this thing, and see what happens......
By the way..... why am I doing this? The answer to that coming up after the next few posts....![[emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/smile.gif "smile")

Ok, it's time to step on to the aluminum. Remember, this is using Por 15, which is marketed as a paint, to apply to rusty steel, aluminum, and they also say it works on wood.
In this photo, I am just getting onto the aluminum sheet. This is still the same .010" thickness, that I have been using.
Looking at the stop watch in front of the box, we see 15.11 seconds.

So after standing there for about 5 1/2 minutes, with nothing giving way, I decided to get off of the aluminum. I had just barely gotten my left foot on the ground, and the clock is at 5 minutes 47.12 seconds.
Absolutely no movement of any kind between the aluminum and wood box.

After stepping off, I took the box inside and you can get a better look at it.
Absolutely none of the aluminum pulled away from the box anywhere. 350+ lbs, and it held it all.
That is some serious paint.....Lol.

So, I decided to try and pull the aluminum away from the wood box. In this shot, you can see the results of that.
I only worked with one corner, based on the results, of how difficult it was to pull this back.
Looking at the green circle in the middle, you can see where the wood stayed adhered to the aluminum.
The 3 red circles, show what happened to the aluminum when I stuck a screw driver in there and tried to pry it up. Left some serious dents in there, and didn't move the aluminum a whole lot.
Also of note, is the yellow circle. Upon prying some of the aluminum up, it tore the aluminum, instead of it pulling it loose from the wood.
To say that this stuff was stuck much more solidly than the speed grip, would be an understatement.

So, what am I saying?
Well, I am NOT saying that the Por 15 is better than the Norton Speedgrip.
What I am saying, is, the way that I prepared the metal and wood, the Por 15 was way superior to the speed grip.
If I prepared the metal differently, the results may have been different.
All I did, in both cases, was to sand the aluminum, and the wood, to get a slightly rough surface, instead of a smooth one, then wipe it off with lacquer thinner.
I then applied the speed grip or the Por 15, let it cure, and then stepped on it as my test.
Definitely not necessarily all that scientific.
However, for my needs, and the ease of use, Por 15 will do the job I need just fine.
Neither one of these are cheap by any means, but the Por 15 will cost less and go farther for what I want it for, by a long shot.

By the way, here is a picture of the top side of the corner which I pulled up with a small screwdriver.
Yup, poked a couple of holes completely through, which was not visible from the underside of the other picture.

I have 1 more test to run on the aluminum with Por 15 to the wood box. Will try to get that posted tomorrow.
In the mean time, we have here a piece of plywood.
It is partially coated with Por 15.
Pic is so you can see what is under the paint.

Here is the next pic with the entire piece of plywood covered with several coats of Por 15.
This test will end up being conducted by weighing this block before doing anything.
Then, next, by boiling it in water for a period of time, remove it, then wiping it off, reweighing to see if it picked up any moisture.
Then throw it in a freezer for a night.
Then, just like your shampoo - lather, rinse, repeat.....Lol.
We'll see how this holds up after several boiling/freezing cycles.
