stick some adhesive foil to it (like the ones u us to protect book covers) and peel it off again. All the dust will stick to the foil and the silicon will look like new. One of those rolls to clean clothing might work as well

Does anyone know where I can buy Lexel or something similar (any recommendations?) in Germany? Unfortunately amazon.com doesn’t ship Lexel to Germany. Additionally I could not find Toluene/Toluol in German DIY stores. I have requested it today in a pharmacy and they will call me back about availability. Anyway I think this will be quite expensive. Does anyone know a “good” source for Toluol in Germany???

I tried to use cleaning solvent in combination with transparent silicone instead but after the solvent has dissolved the silicone layer is unclear, uneven, takes ages to dry and remains somehow sticky.

Thanks,
johannes

Mj--- Personnally a clean it out with water and soap but I had to let it dry for some days. I tried the next day and there were still some moisture beneath my rosco and silicone so it was sticking together. I have put some newspaper over it and let it dry for 5 days… I definitively suggest you not to do like I’ve done because it was a real hassle. I have not tried jakob.leitner way but It seem far better than mine… lol

lagerkoller--- I think Adam have made it with lexel. Im sorry i cant help you more than the link I’ve posted before.

Been able to buy a litre of Toluol in the pharmacy for 17 Euros. I mixed that stuff with transparent silicone caulk for bathrooms from the DIY store and poured it over a crap piece of acrylic. Still the same problem: The stuff gets blind when it cures out. Maybe that happens because of the anti fungal stuff in the silicone or whatever (tried two different brands).

Anyway I’m fed up with this. I placed my order for Sorta Clear 40 at kaupo.de yesterday. Hopefully that turns out to be successful for me. Or maybe I will be a lucky guy and find out a source for Lexel or some other working caulk in the meantime…

UK Lexel

I found this site that sells Lexel in the uk

http://www.marine-super-store.com/posit/shop/index.php?category=3&group=3&offset=72&searchtext=&manf=&format=2&sortorder=1

Do you guys think this will work

Also does anyone know where i can buy a clear silicone sheet in the uk it would save me having to make my own.

lagerkoller - Sorry for bad results… If your silicone is not toluene based it will lead to your results…

Alexis - Lexel works adam used it with success ask him. Dont know nothing about rubber sheets…

Thanks
Chris

Hey guys,

I’m trying out the Lexel method right now. Bought some at a local hardware store, mixed it with the Toulene, and everything seems to be going well thus far. My only problem is with the smoothing. We made an attempt, and ended up with a lot of uneven stuff.

Do you think this substance would work in a paint sprayer like the way Christopher originally describes? Or, does the Toulene splashing method work really well ?

Thanks,

Riley

Surely it will works for sure..... Simply to thin it to the right flow property!

Hey Chris,
I had a question, how thick did you make the silicone layer when you sprayed it on?
was the thickness even, if it was even how did you get it even i practiced on a mirror to see if i could used the method you used but i’m not able to get a level surface.

Thanks
Taha

Hi taha… you have to spray many thin layers.... and let it dry between them (you shoot the next layer when the other dont look wet, dont wait 20 minutes between layers it should take 2 a 3 minutes). For the thickness my result shown the thicker your rubber is the more ftir effect will be lost… What i mean is the screen will be brighter to your webcam and you will loose sensibility… Best results were between 10/1000 inch and 7/1000 inch. Took about 10 layers of spray to get this thickness....

Hope it help
Chris

Nobody tried spray silicone (or similar) like this: http://www.eco-servicesrl.it/a_6_IT_58_1.html ? (this is italian, but for sure is available in the rest of the world).
i’m italian, i found toloulene here: http://www.zetalab.biz
Anybody know where to find lexel and rosco screens in italy? or a website that sell lexel and rosco screens online?

Sorry, but I’m a little confused… Do you have to mix the caulk with toluene for it to work on a touch-screen? Is this what you did, or is it just a suggestion? What I’m asking is if I can manage with just the caulk, and if it will lose quality with just caulk.

No you are not obligated to thin it but it will be a lot more easy to apply a thinner layer with a more liquid caulk this is why I thin it. You could pu 1 mm of caulk but your screen will be brighter to your camera and the blob will have less contrast with the rest of the screen so you will loose sensibility… The caulk settle a little bit of the ftir effect the more you put the more effect will be lost…

Hope its clear enough.

I applied the Toluene solution to my plexi yesterday afternoon…

I found that the easiest way to get rid of air bubbles was to blow at them.  Not to hard or you create more but a burst just enough to spread them out and pop them.  Unfortunately blowing out put me in the predicament of having to suck air in to my empty lungs right over my big puddle of Toluene.  I’ve never gotten high from huffing before… It resulted in a small headache and a captain jack sparrow equilibrium that lasted for a few hours.

Anyway, I think my layer is to thin.  I went a little over thin on creating my mixture so that i wouldn’t have the spreading problems some people have run into.  Because of that a lot of the solution leaked out around the edges that I had constructed from “foam core.”

Now I have a very very thin coating over the entire surface… Do you think that will be enough? I’m not even sure its up to the 7/1000 of an inch proposed by Christopher.  I’m sure it wouldn’t be removable in a large sheet like I saw in that one video.  It so thin it simply makes the plexi feel just a little rubbery.

Maybe I’ll add more this afternoon after finding a better way to prevent run off.

Try it..... Its the only way to know..... Yeah toluene should not be breath..... lol can make people dizzy.....
Just for you to compare an hair is 7/1000 so if its more thick than an hair....
