I've been working on my sintra Jango chest armor the pat couple of days and I just got to rub n buff it today. It's plain sintra that I sanded with 600 grit, primed with Rustoleum professional grade primer (or something like that; it was definitely Rustoleum), I sanded that with 600 grit, and then I wet sanded with 1000 grit. When I rubbed the silver on I tried my best to imitate what Seeker did in his video tutorial, then I buffed each piece for 10 minutes with an old t-shirt and for the most part I'm pretty happy with my results.
There's just one area in the middle of the right chest piece that did not come out well. Every time I try to put more rub n buff on it just doesn't stick. There are some smudges like this on the other pieces, but they're much smaller and less prominently placed so they seem more natural I guess than this one. Can anybody help me out here with getting this one area fixed?
