Here is a great conversation on that topic: http://www.hometalk.com/activity/56624
Sandy, There has been several discussions here on Hometalk about Rustoleum, the transformations are pretty good but there no information on its longevity, only time will tell. This is a new product and claims to transform your cabinets in a cost effective way. I'd suggest this product for flippers and owners who rent homes.
You need to keep in mind that this is still just a "paint" job...sometimes refacing is a few notches up.
I used general finishes gel stain to redo mine. I feel it is much better this. Paint because it won't chip.
