Yes. Thurston James has a plethora of wonderful instructional guides for these kinds of things. I wouldn't use that wood flour mixture on a helmet. You might end up with just a big mess to clean off of your bucket. www.smooth-on.com is where I get my mold-making materials. If you order a starter kit, it will come with your mold rubber, liquid plastic, release and sealing agents, and a small instructional guide. Silicon is the preferred mold rubber for casting something like a helmet. From smooth-on I recommend the rebound 25 brushable silicone rubber. You measure it by volume, so you won't need a scale and a trial size should cover a helmet. You would also need to pick up the proper release agent. Silicone is good about not sticking to anything, but it's better to be safe when covering your bucket with goo. Have a look around their site. They have pretty much everything you'll need. One thing tho. Just keep in mind that plasticene clay with retard the curing process of the silicon.
