I finished Sean's goggles yesterday. I think they came out pretty spiffy. I used fake suede fabric to cover them and some of the rustoleum gold paint that I had.
I did run into a slight problem with the glue I used for the first goggle part. Even though it said it was good for plastic, it started eating away part of the plastic, and was very messy. So for doing the other half, I used permanent double-sided tape, which actually worked out great.
Here's what I started with - Hobart Welding Oxy-Acetylene Goggle (50mm Eye Cup #770096) - from Amazon.
And here's how they look now.
