What's the difference??? (Molding Silicone)

I recently ordered some molding material, and when i got my order i realized i got the wrong stuff:disappoin, what i thought was RTV-1000 silicone, was Flex-50 the clear stuff. And i decided to give it a try. So what the difference in molding quality, and the detail it catches? Silicone seems like its better, so what do you guys think?:rolleyes:

I think that I'll happy with two thing: peace in the world and if people use adequate titles in threads ;) :D

There are some other few things that can't be written (at least here) :D LOL

Oki, just like the little cherry in the cake, I'll happy also if people stop to bump old famous stuff: everytime I run to see fabulous updatez ;)

May be I'll be happy also if mods don't clear my post, but since I love them I'll happy also w/out :D LOL

Personally, I'd like to find a mold material that is super thin, but as of yet, I have no had no luck.

As far as which is better, I'd have to take into consideration what kind of part I'm making, and how many. I'd have to choose the one with the most elasticity, and thinnest viscosity for the stuff that I'm casting. However, if you are casting large parts with little detail and no undercutting in the mold, a stiffer rubber would likely be a better choice.

Also you have to consider the type of material you are using for a master, and casting material. I'm not sure if silicone, or rubber will effect any of your standard casting resins, but I know that some of the materials one would make masters from would effect the mold material making it not set up, or hardening it leaving cracks, swirls and what not in the mold.

I guess it's just a matter of trial and error. I found that although alumilite is fine for casting limited detailed parts, and larger pieces, it is no good for casting motors, radiators, wheels, or any other parts that have fine, intricate details, unless you have a vacuum chamber to get all the air out of the mold.
