I should have been more clear. I wanted to point out that this company was "NOT amateur youtube stupidity" The Reynolds Advanced Materials, a division of Smooth-On has been around since the 60's, and as stated above Smooth-On has been around forever.
I sold and used a lot of Smooth-On when I had the store in Ohio and thought it to be a great product.
Nothing beats hands on .... plus you get a starter kit and they feed you.
