Sorry been busy with life. But it is styrene....I think that is the correct spelling. I bought a 4 x 8 sheet of it about a year ago when I was going to do a RFT helmet costum run. Never the less, the patterns were based on the pics from visual dic. and other pics laying around. Now, I'm bigger then the actor "Tem" so my armor should come out looking correct to my body size.
But I did the patterns out of thick paper and then cut the 1/4 styrene with my band saw. Later with leather gloves on I took a heat gun and started forming the shapes. Then, I sanded them down. 180 grit, then 220 grit and last 400 grit. After that it was all about the rub and buff.
Here is my tip for Rub and buff.
"Use your figures! Spread the past evenly with no build up. You must lay a even smooth base first! Once it is even with no build up or low point with not enough product. Then with a soft cloth gently buff the shine in only when it is even."
