what should i use to spread the silicone over the foam with? i thought about using my hands.... but it seems like it would be a huge mess and ineffective to boot...
I would use cheap artist brushes, you can get them dirt cheap at Walmart and other stores.
Don't get it on your hands - besides being super unhealthy, it's very, very hard to wash off. It's very bad to breathe in, too. If I get any on me, I wash with mechanic's grit soap and Lemon Joy, and it's still hard to remove.
