Have you taken apart a set of the OEM housings for the Gen 2? The few people that I have talked to said they are pretty hard to take apart with the permaseal. I'd be more than willing to do it if I know I'm not going to ruin two housings, because that's $1,000 out the window. Maybe more depending on shipping.How do you know any other brand is not sealed? Just put it into the oven and it should come off easily. When reaching room temperature again you can rub it off. The question is where to find a replacement seal...
