Are they all about the same? I was planning on ordering the Brownells gel bedding kit, its about 2 dollars more than the regular kit, and supposedly easy to use. I'm not bedding a magnum so I dont think I need one of the kits with powdered metal in them.

as far as I'm concerned Brownell's is the stuff to buy

I have a big box full of glass bedding products. They range from:
1) Thin and runny, cheap [$10/quart at Home Depot], stinky, Bondo all purpose fiber glass resin

2) Thick, expensive [$23.75/ pound], no odor, Devcon Plastic steel putty
