I've been experimenting with silicone.
I found that silicone 2* / 2*+ [ammonia cure]
is very flexible in terms of the stuff you can do with it.
You can add dye to it.
It will adhere to itself if you need to go back and apply extra
you also can make it cure faster by vigorously mixing it before applying.
You can thin silicone 2* by mixing in silicone oil.
You can give silicone 2* a gloss like finish by adding silicone oil to the surface and then brushing over it with a popsicle stick.
I also experimented with silicone 1* [vinegar cure].
I found that silicone 1* won't mix with oils and it won't adhere to itself.
It sets too fast if you pour hot water over it. it also yellows for some reason and takes a long time to get rid of it's odor.
Silicone 1* is probably not the best for a bathroom, however it might work well as an adhesive to hold something to a flat surface.
Although silicone 2* takes longer to cure, it doesn't yellow which would help if you're using white silicone.
Note:I'm referring to GE brand silicone.
