I bought this product a while ago, but just recently started to learn how to use it, and man, I
should have started sooner. You watch the DVD and learn some effects, and then put your mind to it!
I love this stuff! I recently bought a very popular trick that utilizes roughed cards.
The first time I was practicing, because of the lighting I noticed the spray marks of the roughing
spray on the card. Science Friction leaves no residue that I have been able to detect.
If
you are a hobbyist like myself, it makes a double turn-over so easy to do without even having to do
a break! :)
Pricey? Maybe, but have found it worth the price so far.
