Ok need a rubber that will withstand gas, oil, and heat any help with this and if silicone will work what will be the best to use ty

@slickster3100 All urethane and silicone rubbers will absorb oil.

Also something to mention about Silicone, since silicone sticks to silicone you could brush the first coat of silicone on the project first THEN come back to it and pour the rest so air bubbles are not a huge problem.. this video is great but the only flaw is the Vacuum degassing machine will scare off ALOT of people.. with a simple brush on coat could take alot of the problem away.. yes a vacuum machine is awesome but at 800-1000 dollars not everyone will invest in one..

I should have taken up basket-weaving instead.

It says I can't pour latex? I've been doing this for years, but with a split mould. Did you mean you can't pour a glove mould with latex? I'd really like to try.

@muppetspuppets Hey man, if your´re formiliare with it can I ask you something; do you have to use a release agent/spray for molding with latex? Because I bought a can op Latex Rubber ( I think, the package only says liquid rubber :P ) and I didn't use a release agent, making a 2 part mold by the way :) Hope to hear from you soon :) Gr Bob
