I sprayed this in my armpits to save on deodorant. I'll report my findings.
I'm sorry to report that Juice has died from hyperpitsweatosis.
Just sprayed a test vehicle with the stuff. My first impressions after de-masking are impressive. I just did a 5x7 index-card-sized square on the front bumper, and a little square on the window (to see how clear the stuff is on the car).
The material is visibly thick even 1 minute after spraying. The lines stay relatively sharp, and there is a clear "step" up from the paint of the car.
I'll update later on how it settles.
The biggest problem I can see is that even if you do this in your garage (which I did) little debris/dust can get into the material while it is drying. It already happened to me. You'd need a clean room for a perfect application.
Also be careful how you tape the edges. Don't criss-cross the tape (i.e. don't have the left side go under the top piece, and over the bottom piece; etc.etc.). I did this, and ended up having to take all the edges off as one giant piece of tape, instead of individual strips).
Also lay down the tape with the newspaper/plastic wrap first, choked up just a little bit before your final "edging" layer of tape. This way, when you lift, you won't have to lift the newspaper, which can mess up the polymer if it brushes it (ask me how I know).
Good thing I tested this out first.
It worked very well without any special spray nozzles. But then again, I only did a small area. Have some extra cans in case
**4 Hour Update**
Ok, I checked at 2 and 4 hours, and the material seems to have settled down (not as thick) and is MUCH more clear than it was after initial application (so don't worry about any haze/uneven spots after applying). The bad news is: Judging by how thin this is, I seriously doubt this material will protect against anything besides paint oxidation/extremely minor debris.
At 4 hours, the polymer is nearly invisible. With the naked eye, I couldn't even tell. I had to use my phone's flashlight to see the edge, and even then, I had to angle it right to find it.
I will keep an eye on it and update, but I am disappointed with how thin it is. If you think about a regular leather/pleather bra, it not only has the leather which is several mm's thick, but it also has that felt liner in the back. I would say the total thickness is ~5-10 mm thick, with a lot of give and shock absorption.
I have never seen a regular clear bra up close, but from videos, it looks substantially thicker than this polymer.
I am going to let that first layer cure, then add a second layer tomorrow.
*the area I sprayed on the window turned out completely clear.
