A question was asked about the rubbers feel on my other thread, and i felt it was also relevent to this thread, so i will also add the answer here....
It didnt change in texture or feel once submerged that i can tell, which is a good sign. I wouldnt say it is spongy, but its not hard like a plastic either. Between the two, i would say it is closer to a hockey puck, with some give. like silicone, but slightly harder. once cured it still reamins tacky for a while, but losses that within a week or so. Im not sure if it means its still cureing or not.
I did a test with this stuff befor the build started for a few reasons. One was to check if it would change colour once submerged like liguid rubber states. It didnt during the test of a couple of days, but now that it has been in the tank for a few days, it is starting to turn brown. i dont mind it at all, in fact, i think it looks great. Since i put mine one with a normal brush for one coat and left horrible looking brush strokes(or so i thought) and with the rubber turning a bit brown, it almost looks like tree back now. So i think it actually now looks like a nice background.
