I can only speak on what I know for certain..... Caswell has "fresh" powders and they are stored well until you are ready to buy them. They are used industrially under the trade name H.B. Fuller worldwide with no problems. I have no clue where Eastwood gets all of thier powders from but storage and proper handling are more the key here than anything else. Yes, all powders that you guys spray are *basically* the same and can all be applied electrostatically. As far as buying powders from individuals over the ebay type sites, I generally don't. It costs next to nothing a pound for a reason. You have no clue how old it is or where it's been stored properly, if at all. Do you want to put all of that prep effort into your parts ( or worse, a customer's parts?) and put a cheap defunct powder on top and have to strip it? I didn't think so. The best bet is to stay with a proven winner in the field of powder coatings whom you can rely on. I can speak firsthand after using a lot of the products here.... Caswell is that very company ( not to mention, you get the joy of talking to all of us... who can beat that?
