I am in the process of creating my first fett costume head to toe. My wife bought me a bucket on eBay, (I only now know all about recast and so forth please no flames) I had to do a lot of thinning the inside down to get it to fit. I mean a ton of work and it still is hard to get it on my head, it's not that big I swear. Anyways in the process of thinning it down I cracked on cheek about and inch and wore a thin spot in another. What do I use to repair it? Please dented helmet you are my only hope!
