I got in on EW’s “free powder” thing a few weeks ago. Hi-temp Silver was in my potluck sample batch.
My question is about the finish. The first and only parts I’ve shot with this powder were two lawnmower cylinder heads and an old Sears air compressor cylinder. They turned out fine and since all were cast iron or cast aluminum I never gave it a second thought. THey seem normal for cast items.
But last night I shot one of my samples using the beer bottle method and the thing seems to have a grainy texture to it. Almost like 400 or 600 grit wet-or-dry sandpaper. And it’s a very consistant texture all over. Is this normal for the the hi temps? Do all the hi-temps colors do this? For some reason I was expecting the smooth glass-like finish you get with most of the standard and candy colors. Or did I just screw something up royally?
