I used a bunch of it years ago and did not have a good experience. Purchased all the expensive prep stuff and the paint and followed the directions. Last year I used a hand scraper and scraped a bunch off that had rust bubbles forming underneath it. Ironically, stuff that I painted around the same time using a cheap rattle can has held up better.

In my opinion this stuff does not live up to the hype and is not worth the price. When it does stick, it is difficult to remove. Therefore, I'd rather use a regular paint that will likely hold up better and will be easier to remove later if I want to freshen a part up.
