Aluminum powder is becoming very expensive these days, especially on eBay. Thus, many people have decided to try to make their own. However, this information is not easily available on the net. Some sellers began to sell guides on eBay on how to make Aluminum and Dark Aluminum Powder. The original sellers were Tiggerstore and Pyroguides. Now, Tiggerstore and Pyroguides have joined forces to sell one guide will all the information on both guides. Many people have tried to steal this information and sell it on their own but their accounts have been suspended from eBay. When you buy the Aluminum Powder guide from Pyroguides, you get a year of technical support (It isn't even needed for this guide) and his feedback guarantee. This guarantee is that he leaves feedback automatically the second you pay for the guide. Then, you don't have to worry about being completely honest when you leave feedback for Pyroguides. Every single buyer of this guide has been very happy and left positive feedback. So if you want to buy a guide to make aluminum powder, buy it from pyroguides. Hope this helps!
