Brad and Lacy are good guys, and they try hard to make a good product. If you ever have a bad piece, they will replace it.
Due to the way it is manufactured, Alabama damascus is a slightly looser layered product than the much smaller billets many folks make. Now, that is not really bad, and the cost is really good, so the trade off is that you will have tiny pits and layer lines to deal with. It is an excellent product for first time damascus projects when people are leery to spend a couple hundred dollars in steel on a knife they aren't sure how it is going to turn out. It isn't the steel of choice for some projects, but is an affordable choice for general use damascus knives and tools. I find it looks best when deeply etched. I have probably used 100 feet of their stuff, starting with the first batch Brad made nearly ten years ago. I still buy it for suitable projects. They will also custom make a billet in odd sizes to order. If you want to mill a sword guard from a block of 1X2X8" damascus, they can probably sell it to you cheaper than you can make it yourself.
The following is good advice for all damascus.
The first thing to do is remove all traces of etchant from the recesses in the steel. Just spritzing on Windex won't do it. Boiling for 30 minutes in water anda little soda, and then boiling again with plain water will help keep corrosion spots from showing up later. Next, you need to remove any retained water from these tiny places, or rust may creep out. Placing the blade in the oven at 300F for an hour will do that. When the hot blade is taken out of the oven, let it cool to about 150F, and immediately oil it well with a protective/penetrating oil. This will wick into the recesses and keep water from getting back in later.
Sealing the recesses from invasion, with a coating of some sort as Chuck described, is also a suitable plan.If you are going to seal the blade, skip the oil impregnation step.
The raised surface can be sanded back to metal, and the recesses will stay sealed. This really gives a bold two-tone look.
Regular maintenance will help keep things rust free.
