I had to purchase my first can of 505 spray at my LQS because the JoAnn's I usually go to "never heard of it"....... I bought the smallest can sold because I wasn't sure I'd like it or not, and didn't want to go into "debt" and be stuck with something that I may or may not ever use again after my initial try. That being said....... I LOVE 505 spray!!!! I think the only trick is that you have to use it VERY, VERY sparingly. I would almost guarantee that once you've tried it, you'll never go back to the tedium of pinning.
