Hi everyone
I've been lurking here for a while soaking up info on casting and powder coating. Full disclosure, I'm a complete noob to casting. So last week I finally dusted off the equipment I got second hand a few years ago and casted some 158gn RNFP from a 6cavity Lee mold. The alloy came from clip on wheel weights that I melted down, cleaned and fluxed, and poured into muffin ingots per directions I found here. After a bit of trial and error, I started getting some halfway respectable projectiles. So today, I got some Eastwood Ford Light Blue hotcoat, gave them a spin in the tumbler for about 15min, popped them in the oven at 400f for 20min, took them out and dropped them in water....and it does not look good. Poor coverage, coating kinda peels off, lots of bare spots. So, two questions. Where did I go wrong, and what do I do now? Can these be salvaged, or do the go into the pot next time I melt wheel weights?
